Suspension Tuning Guide-Learing The Lingo

To ride like a pro you've got to talk like one

                                Every activity has its own language. Learning a new skill sometimes feels as if it
                                requires scaling a linguistic learning curve that makes surmounting Mt. Everest
                                seem like a day hike. To the uninitiated--not that any Sport Rider reader could
                                be accused of this--the language of motorcyclists can seem just as daunting.
                                So, to make sure we're all standing on top of the same hill, peruse the
                                terminology below to help speed yourself along to suspension enlightenment.

                           Bottoming (also called bottoming out)--when a suspension component
                           reaches the end of its travel under compression. Bottoming is the opposite of
                           topping out. Cartridge Fork--a sophisticated type of fork that forces oil through
bending shims mounted to the face of damping pistons contained within the fork body. The primary
advantage of cartridge forks is they are less progressive than damping rod forks. The shims allow damping
control at very low suspension speeds while high speeds deflect the shims more--causing less high-speed
damping than fixed orifice damping rods. The resulting ride is firmer with less dive under braking while
simultaneously lessening the amount of force square-edged bumps transfer to the chassis.

                                Compression Damping--controls the initial "bump stroke" of the suspension.
                                As the wheel is forced upward by the bump, the compression circuit controls
                                the speed at which the suspension compresses, helping to keep the spring from
                                allowing an excessive amount of travel or bottoming of the suspension.
                                Damping--viscous friction caused by forcing a fluid through some type of
                                restriction. Damping force is determined by the speed of the fluid movement,
                                not the distance of suspension travel.

                           Damping Rod Fork--a simple type of fork that
 This is DAMPING utilizes a tube with holes in it to create compression
                           and rebound damping, delivering an extremely
progressive damping curve. The faster the wheel moves vertically, the more oil
that is shoved through the holes. Typically, damping rod forks have very little
low-speed damping and a great deal of high-speed damping. The ride is
characterized by excessive fork dive under braking and hydraulic lock when
encountering square-edged bumps. Any change to the damping rod system,
such as changing the size of the holes or altering the oil viscosity, affects the
entire speed range.
                                                                                       This is
Fork Oil Level--the level of oil within the fork as measured when fully                DAMPENING
compressed without the spring installed. It is used in tuning the amount of air
contained inside the fork. Since compressing air makes it act as a spring, raising the oil level leaves less
room for air, resulting in a rising rate throughout the fork's travel. Reducing the oil level reduces the force
at the bottom, giving a more linear rate.

                                Free Sag--the amount the bike settles under its own weight. Both streetbikes
                                and race bikes require 0 to 5mm of free sag on the rear. The bike should not
                                top out hard.

                                High-Speed Damping--damping to control fast vertical movements of
                                suspension components caused by road characteristics such as square-edged
                                bumps. High-Speed damping is independent of motorcycle speed.

                                Low-Speed Damping--damping to control slow vertical suspension
                                movements such as those caused by ripples in pavement. (This is also

                            relative to vertical, which varies with changes in ride height. For example, the
                            rake angle decreases when the front end compresses or is lowered. Changes in
                            tire diameter can also influence rake by altering the ride height.

                            Rebound Damping--controls the extension of the fork or shock after it
                            compresses over a bump--hence the term "rebound."

                          board in the riding position. Sag can also affect
steering geometry. Extra sag on the front end will decrease the effective
steering head angle, quickening steering, while too little front sag will slow
steering. However, too much front sag combined with too little rear sag could

                            Topping Out--occurs when the suspension extends to its limit. A shock with a
                            spring of the proper rate mounted should have just enough force to top out

Suspension Tuning Guide-Handling

How To Get It

Trying to figure out a handling problem can be tricky. It's hard enough dealing
with the intricacies of spring preload, rebound damping, etc., but when a
definite problem forces you to back off the throttle and take notice, trying to
determine the root cause of a handling difficulty can be downright baffling. Is it
the front or rear causing it? And how do I know if rebound or compression
damping adjustments will help?

In this section, we've come up with some of the most common handling
complaints that afflict the average rider. Some of these problems occur entering
the corner, some of them happen in midcorner, and others can even cause
difficulty exiting a corner. Take a close look at the various problem scenarios we've listed and see if one of
them sounds similar to a dilemma you've been struggling with. Then try our suggested solutions to see if
they make an improvement. Remember take it one step at a time, take a test ride after each change, and
take notes on whether that change made a difference.

                           TERRY TANKSLAPPER

                           Problem: Terry's bike feels unstable, especially when entering turns. The bars
                           seem to "twitch" excessively whenever a midcorner bump is encountered. The
                           bars often whip back and forth violently several times (or more) when Terry is
                           accelerating aggressively over bumps while coming out of a turn--in other
                           words, a "tankslapper." The bike steers very easily, although a lack of traction
                           is sometimes noticeable in the rear whenever he tries to accelerate at moderate
                           lean angles. The bike also seems to have a dropped-down, "nose low, rear-end-
                           high" attitude while riding.

Solution: The biggest distinguishing factor in this case is the "nose-low/rear-end-high" chassis attitude
feeling. If Terry's bike definitely feels this way, then probably he has too much front end weight bias. This
not only hinders traction at the rear, but also affects the steering geometry (steeper rake/less trail) and
can cause the instability problems. As long as Terry has his suspension static sag levels set correctly, the
first step is to try less rear spring preload and/or more front preload, to the point just before they begin to
affect handling negatively; Terry should remember to adjust his rebound damping if necessary (in fact, he
should check to see if decreasing the front rebound damping in small increments helps; the forks may be
too stiff, hindering traction). If only partially successful, a more drastic step would be changing chassis
ride height; this would involve raising the front end by dropping the fork tubes in the triple clamps (if
there's enough material protruding above the top clamp, to ensure front fork structural integrity), and/or
dropping the rear by shortening the rear shock (if possible).

Note: We've also seen a tankslapping tendency produced by too much rearward weight bias. Terry might
try working the opposite of the preceding paragraph solution, or check out the understeer/no front traction
problem scenario for more suggestions.

MARSHMALLOW RIDE MIKE

Problem: Although Mike's bike has a very smooth ride while riding over
potholes and such in the city, once he's out in the canyons, his bike seems to
"float" over the pavement like a luxury car, with little or no pavement feedback.
When he starts to ride aggressively, the bike rocks back and forth excessively,
especially during brake/throttle transitions, and the "floating" feeling becomes
even more pronounced. Hard cornering makes the bike feel loose, almost as if
it has a hinge in the middle. Mike's tires might begin to chatter midcorner when

Sport Rider-Suspension Tuning Guide-Handling                                                      Page 2 of 3




encountering bumps and accelerating over those bumps causes his bike to
wallow or weave.

Solution: The problem here is generally not enough rebound damping. The ride is smooth and supple at
low speeds, but higher speeds generate greater amounts of energy that can't be dissipated with the little
damping available. As a general rule of thumb, if either end is pushed down firmly and quickly by hand,
the suspension should return in a smooth, controlled manner without "rebounding" once or twice before
settling down. Mike should try stiffening up the rebound damping in small steps, and remember to do the
front and rear separately, not simultaneously; that way he can readily see if one or the other makes a
difference. If Mike has the rebound damping cranked up to the maximum and his bike still feels soft and
wallowy, he may need to rebuild the suspension components.

                           REAR-SWAPPING RICHARD

                           Problem: When Richard gets on the brakes aggressively while approaching a
                           corner, the bike's rear end begins to swap side-to-side, and feels as if it wants
                           to pivot around the front.

                             Solution: The cause here is way too much front end weight transfer under
                             braking. The front end is compressing so low that the bike's weight tries to
                             pivot around the steering head, causing the side-to-side movement. The
                             quickest solutions here are to increase the front fork spring preload and/or raise
the front ride height by dropping the fork tubes in the triple clamps, or decrease the rear ride height by
shortening the shock (if possible). Richard should try increasing the fork spring preload first, and
progressing in small increments until the handling begins to be negatively affected (remember to watch
the rebound damping when increasing the spring preload). If that doesn't work, Richard should try the ride
height modifications; watch for adverse handling reactions in other areas when doing this as ride height
changes drastically affect how the bike corners. Other solutions to try--although less effective--are to
increase the compression damping in the forks (if possible), or to decrease rebound damping in the rear
(to allow the rear tire to follow the pavement quicker). Again, Richard should watch for adverse handling
reactions in other riding situations when test riding.

ROUGH RIDING RICKY

Problem: Ricky complains that his bike is uncomfortable and he feels every
little bump in the road. He doesn't have any confidence because his bike feels
nervous and twitchy, especially over bumpy sections where it doesn't absorb
the bumps, and his tires lose grip easily. Diving into corners during track days,
Ricky's bike is unstable and jumps around over every little bump and crack in
the tarmac.

Solution: The rough ride Ricky is experiencing is most likely due to a generally
too-stiff setup--with too much compression and rebound damping. First off, Ricky should set his rebound
adjusters as outlined in the setup section, and back the compression adjusters out to no more than the
middle of their range. This will give a starting point to work from, and get rebound damping in the
ballpark. Dialing in the rebound more accurately can be accomplished by riding the bike over a rough
section of pavement; the suspension should not pack down (too stiff), nor should the bike be wallowy like
a Cadillac (too soft). Riding the bike repeatedly over the same road after making small changes to the
damping adjusters is a good way to distinguish between the characteristics and determine a good setting.
Once the rebound is set properly, the compression damping can be fine-tuned according to the setup
section. Once again, Ricky should make small changes between test sessions over the same road to help
him feel and compare the different settings.

                           BOTTOMING BARRY

                           Problem: When Barry brakes hard approaching a corner, the front fork
                           bottoms out severely, especially over bumps. However, the fork action and
                           overall bike handling is fine everywhere else.

                           Solution: The problem here is Barry's ride height is set up correctly for his
                           riding style, but the fork action is obviously too soft whenever weight is
                           transferred to the front (as when hard braking). Barry has stiffened up the fork
                           spring preload before, and while it helped with the bottoming problem, it




http://www.printthis.clickability.com/pt/cpt?action=cpt&title=Sport+Rider-Suspensio... 18/06/2006
Sport Rider-Suspension Tuning Guide-Handling                                                           Page 3 of 3



unfortunately made his bike's chassis attitude too front-end-high, adversely affecting handling. The cure
here would be to raise the fork tubes in the triple clamps (starting in increments of 4mm), which lowers
the front end; Barry could then increase fork spring preload without causing the ride height problems
mentioned previously. Care should be taken to ensure that the front wheel/fender isn't getting too close to
bottoming out on the lower triple clamp or radiator when lowering the front or raising the fork tubes. If the
preload adjuster becomes maxed out during testing and dial-in, a set of heavier rate springs or a larger
preload spacer (inside the fork) may be necessary.

HEAVY HANDED HANK

Problem: Hank says his bike's steering feels super heavy at low speeds, and
once he gets his bike turning by using lots of muscle, it practically falls into
corners.

Solution: These characteristics could be the result of a squared-off rear tire
(too much straight-line riding) or notchy or too-tight steering head bearings; if
Hank has a steering damper mounted, it may be adjusted too tight.
Suspension-wise, heavy steering is a typical result of having rear ride height set
too low, raking out the chassis like a chopper.

If Hank notices the same troubles after trying his bike with the steering damper backed off, checking his
tire and adjusting his steering head bearings, the problem is most likely in his bike's chassis attitude.
Front and rear sag should be checked and set correctly, followed by another ride to check for any changes
in handling. If there is little or no change, Hank will have to gradually change his geometry by either
raising the fork tubes in the triple clamps or--if he's lucky and has a rear ride-height adjuster--raising the
rear of his bike. When dropping the front end of a bike by adjusting fork height, it's a good idea to keep an
eye on clearance between the front tire and radiator, and also--on a conventional fork--to ensure the
sliders don't bottom out on the lower triple clamp.

                                  UNDERSTEERING ERNIE

                                  Problem: Ernie is having a lot of trouble with his bike's front end, especially
                                  while exiting turns. His front tire loses traction and pushes to the point where
                                  it's washed out on him a couple of times. He notes that steering is a bit heavy,
                                  and on uneven sections of pavement the front tire skips over bumps and
                                  threatens to fold if pushed too hard.

                           Solution: The trouble Ernie is experiencing is probably due to a combination of
                           sag and ride height settings that leaves his bike riding high up front. Having a
front tire skip over bumps on the exit of a turn is a sign that the fork is topping out--without enough sack
to allow the suspension to sink into depressions in the road.

Ernie should check his bike's front and rear sag settings to ensure correct spring preload. With the preload
set, he should take his bike for a spin to determine if there's any change in its behavior. If the problems
persist, backing off the front preload will drop the front of the bike a bit, quickening the steering and
letting the wheel track over bumps more effectively. If, however, the fork starts to bottom under braking
with the preload backed off, the fork tubes can be raised in the triple clamps to sharpen the steering while
keeping the original preload setting.

Suspension Tuning Guide-Dialing It In

Dial in your suspension for maximum effect

                             STREET

                             One of the major keys to a successful suspension setup is the condition of the
                             components. Before attempting any setting changes, check to make sure your
                             bike's fork and shock are in good working order. This includes replacing leaky
                             seals, lubricating sticky linkage bushings, and changing old fork or shock oil. If
                             your current components have more than 15,000 hard miles on them, you can
                             bet it's time for a rebuild. Check your steering head bearings for notchiness or
                             tightness and replace them if needed. And most importantly, squared-off or
                             worn out tires will mask almost any suspension change you make.

The first step to a good setup is setting static sag. For street purposes, front sag should generally be
between 30 and 35mm, and rear sag between 25 and 30mm. Don't vary from these numbers if you're
heavier or lighter--that's the whole idea of measuring sag while you are on the bike. An easy way to check
if your shock spring rate is in the ballpark is to measure the rear "free" sag, that is, the sag without your
weight on the bike. This number should be between 0 and 5mm--with the bike off its stand and on its
own, you should be able to lift the rear end just slightly and top out the suspension. If your bike is topped
out at rest, you need a stiffer spring, because you have got a lot of preload dialed in to achieve the correct
static sag. Alternately, if your bike has a lot of free sag (you can lift the rear a bunch before it tops out),
you need a softer spring. One notable exception to the sag numbers is Yamaha's R1, which has
substantially more front sag to keep the front end on the ground under power. Use the capsules (page 42)
and subjective chart (page 48) to determine if you should mess with your R1's front preload.

Rebound damping can be initially set as follows: With the sag properly set and the bike at rest and off its
stand, firmly push on the triple clamp (don't hold on the brake or push the handlebar) or seat. When you
let go, the suspension should rebound quickly to its original position--but not beyond. If it takes more than
approximately one second for the suspension to return to position, less rebound damping is needed. If the
fork or shock over-extends past its free sag, and then compresses again, more rebound damping is
required. Street riding entails many different pavement characteristics, and the road is generally bumpy
compared to a racetrack, so it's better to err on the soft side if you are unsure. This will also give you the
added benefit of a smooth ride for daily use; you can always dial in a tad more rebound when you get to
your favorite road where the surface is more of a known quantity.

It is difficult to set compression damping without riding your motorcycle and feeling how its suspension
works. What feels nice and plush at a standstill may turn out to be too harsh at speed, and compression
damping is sometimes set by personal preference as opposed to a definite optimum. Start with the
compression adjusters in the middle of their adjustment range, and take your bike for a spin. Working
with the front and rear individually, soften the damping adjuster, and try your bike again over the same
road. Is your handling better? Worse? The same? Try again, this time with the damping stiffer than what
you started with. Continue experimenting, making adjustments accordingly. As with rebound damping, it's
always best to err on the light side with compression, and for the same reasons.

One final check--with your bike off its stands, place your hands near the rear of the tank, and push down.
A well-balanced setup will have both ends of your bike compressing and returning at approximately the
same rate with this push. If the front compresses or rebounds different than the rear, attempt to match
them, keeping within the parameters established individually.

                             TRACK

                             As with the street setup, first ensure that your bike's suspension components
                             are in good working order, and you have relatively new tires installed. One

                           word of caution regarding setup and tires: Don't get dragged into adjusting
                           your suspension to account for tire wear over the course of a track day without
                           taking notes. You'll be amazed at how poorly your bike handles when you put
                           new tires back on and keep the shagged-tire suspension settings.

                         In general, a bike set for track use is stiffer than a streetbike, due to the
                         increased acceleration, braking and cornering forces involved. Static sag for
                         track bikes should be in the range of 25 to 30mm--somewhat tighter on the
                         fork than a street setup. Similarly, compression and rebound damping should
                         be somewhat stiffer. Avoid tightening your rebound arbitrarily; you still want
the suspension to rebound within one second to its static position after pressing on the bike, but not
overshoot.

If you have a ride height adjuster on your aftermarket shock, set it to the same length as the stock unit
for a start. Similarly, begin with your fork at the stock height in the triple clamps. Use the handling
scenarios (page 42) and the chart (page 48) to determine if you need to change your bike's attitude.
Generally, for a track bike with a steering damper, you'll want to quicken the steering as much as possible
by lowering the front end or raising the rear, while still retaining stability and without sacrificing rear end
traction.

For track riding, it's important to take good notes--and lots of them. Along with your initial settings, you
should also write down some baseline figures for things such as fork oil weight and amount, ride height,
spring rates, and so on. Record any changes you make so that you can refer to them later. Also, keep
notes for different tracks--as your setup will change depending where you are and the conditions. Once
you find that "magic" setup, don't be afraid to deviate from it and experiment; you may be able to
improve on what you have, and you can always go back to what you wrote down in your notes.

SETTING STATIC SAG

One of the most important suspension settings is static sag--the amount your bike's suspension
compresses when you sit on it. To set static sag, we use Race Tech mastermind Paul Thede's method,
which takes into account any stiction in the components. It's best to have two friends to help--one to hold
the bike while the other one measures--while you (fully dressed in your riding gear) do the compressing.

First, extend the front suspension completely. Measure from the seal wiper to the triple clamp for a
conventional fork, or to the axle clamp for an inverted fork. Call this number L1.

Sit on your bike in a normal riding position (or racing crouch if you're track-bound), and have one helper
steady the bike. Your second helper should push down on the fork, let it extend slowly and then re-
measure as before. This number is L2.

Finally, the fork should be extended by hand, settled slowly, and re-measured. This figure is L3. Halfway
between L2 and L3 is where your suspension would settle if there were no friction in the system. Static
sag can be calculated as follows: sag=L1-(L3+L2)/2. Repeat this process to determine the rear sag--
measuring from the axle to a point directly above on the frame for each of the numbers. If you have too
much or too little sag, dial in more or less (respectively) preload as needed.

                           STRIP

                           While roadracers set up their suspensions to allow their tires to follow the
                           contours of the pavement, dragracers have an entirely different set of goals.
                           First and foremost, the center of gravity (CG) needs to be kept as low as
                           possible. Second, suspension travel should be kept to a minimum. For
                           dragracers, keeping the front wheel down and the rear tire hooked up leaving
                           the line is all that matters.

                           At first glance, trying to keep the front suspension as stiff as possible might
seem strange, but once the theory is explained, the logic comes through. Dropping the front end three
inches to keep the CG low is a no brainer: Running a low CG minimizes the rearward weight shift as a bike
starts to launch. The lower stance is achieved by disassembling the fork and inserting three inch spacers
between the stanchions and sliders--effectively reducing the fork's ability to extend by three inches.

Ironically, the same desire to keep the CG low is behind the stiff front suspension. Once the fork is




http://www.printthis.clickability.com/pt/cpt?action=cpt&title=Sport+Rider+Suspensio... 18/06/2006
Sport Rider Suspension Tuning Guide-Dialing It In                                               Page 3 of 3



lowered, the preload gets cranked all the way up. Both the compression and rebound damping get dialed
in to their firmest settings. Finally, 15 to 20 weight oil is used to further minimize fork movement. By
keeping the front suspension immobile, the entire forward end of the motorcycle acts as a single unit and
is much harder to lift off the ground. If the front suspension has sag and is allowed to rebound at the
launch, the chassis can gain enough momentum to lift the front wheel off the ground when the suspension
tops out. Instead, a rigid suspension acts as a dead weight helping to keep the tire planted.

The goal of keeping the front tire earthbound does not mean that dragracers want the additional drag the
wheel can put on the bike, though. Many racers run the tire pressure at 35 psi or higher for less rolling
resistance. Also, making sure that the bearings are nice and loose will lessen drag.

The back of the bike needs to be firm, too--but not overly stiff. The lower ride height in the rear can be
achieved by lengthening the rear linkage's dog bone so that the rear of the bike drops approximately four
inches. Although some people think that running a strut instead of a shock will help their bike launch,
Rickey Gadson, Kawasaki Factory dragracer, says that being able to tune the rear suspension's firmness is
critical to maintaining good rear wheel traction. On smooth tracks, the shock can be run stiff, but on a
rough track, the rear needs to be softened until the tire stays hooked up. Bikes with struts will be hurt on
poor tracks. Rear tire pressure should be dialed in to suit conditions, too. Surprisingly, Gadson says he
starts with approximately 30 pounds and adjusts the pressure based on how much traction he's able to
maintain. His theory about tire pressure is that running the most pressure possible--while still keeping the
rear tire hooked up--lessens the rolling resistance of the tire.

Suspension Tuning Guide-Suspension Troubleshooting Symptoms

                         Here are some basic symptoms of suspension damping problems that you
                         might find affecting your bike. Remember these are extreme examples; your
                         symptoms may be more subtle. You may also have to find an acceptable
                         compromise on either end of the adjustment spectrum. It all depends on how
                         the bike's handling "feels" to you.


                         LACK OF REBOUND DAMPING (FORK)

                       The fork offers a supremely plush ride, especially when
      riding straight up. When the pace picks up, however, the feeling of control
      is lost. The fork feels mushy, and traction "feel" is poor.
      After hitting bumps at speed, the front tire tends to chatter or bounce.
      When flicking the bike into a corner at speed, the front tire begins to
      chatter and lose traction. This translates into an unstable feel at the clip-
      ons.
      As speed increases and steering inputs become more aggressive, a lack of
      control begins to appear. Chassis attitude and pitch become a real
      problem, with the front end refusing to stabilize after the bike is
      countersteered hard into a turn.

      TOO MUCH REBOUND DAMPING (FORK)

      The ride is quite harsh--just the opposite of the plush feel of too little
      rebound. Rough pavement makes the fork feel as if it's locking up with
      stiction and harshness.
      Under hard acceleration exiting bumpy corners, the front end feels like it
      wants to "wiggle" or "tankslap." The tire feels as if it isn't staying in
      contact with the pavement when on the gas.
      The harsh, unforgiving ride makes the bike hard to control when riding
      through dips and rolling bumps at speed. The suspension's reluctance to
      maintain tire traction through these sections erodes rider confidence.

      LACK OF COMPRESSION DAMPING (FORK)

      Front end dive while on the brakes becomes excessive.
      The rear end of the motorcycle wants to "come around" when using the
      front brakes aggressively.
      The front suspension "bottoms out" with a solid hit under heavy braking
      and after hitting bumps.
      The front end has a mushy and semi-vague feeling--similar to lack of
      rebound damping.

      TOO MUCH COMPRESSION DAMPING (FORK)

     The ride is overly harsh, especially at the point when bumps and ripples
     are contacted by the front wheel.
     Bumps and ripples are felt directly; the initial "hit" is routed through the
     chassis instantly, with big bumps bouncing the tire off the pavement.
     The bike's ride height is effected negatively--the front end winds up riding
     too high in the corners.
     Brake dive is reduced drastically, though the chassis is upset significantly
     by bumps encountered during braking.

     LACK OF REBOUND DAMPING (REAR SHOCK)

     The ride is plush at cruising speeds, but as the pace increases, the chassis
     begins to wallow and weave through bumpy corners.
     This causes poor traction over bumps under hard acceleration; the rear
     tire starts to chatter due to a lack of wheel control.
     There is excessive chassis pitch through large bumps and dips at speed
     and the rear end rebounds too quickly, upsetting the chassis with a pogo-
     stick action.

     TOO MUCH REBOUND DAMPING (REAR SHOCK)

     This creates an uneven ride. The rear suspension compliance is poor and
     the "feel" is vague.
     Traction is poor over bumps during hard acceleration (due to lack of
     suspension compliance).
     The bike wants to run wide in corners since the rear end is "packing
     down"; this forces a nose-high chassis attitude, which slows down
     steering.
     The rear end wants to hop and skip when the throttle is chopped during
     aggressive corner entries.

     LACK OF COMPRESSION DAMPING (REAR SHOCK)

     There is too much rear end "squat" under acceleration; the bike wants to
     steer wide exiting corners (since the chassis is riding rear low/nose high).
     Hitting bumps at speed causes the rear to bottom out, which upsets the
     chassis.
     The chassis attitude is affected too much by large dips and G-outs.
     Steering and control become difficult due to excessive suspension
     movement.

     TOO MUCH COMPRESSION DAMPING (REAR SHOCK)

     The ride is harsh, though not quite as bad as too much rebound; the faster
     you go, the worse it gets, however.
     Harshness hurts rear tire traction over bumps, especially during
     deceleration. There's little rear end "squat" under acceleration.
     Medium to large bumps are felt directly through the chassis; when hit at
     speed, the rear end kicks up.
