Spring Rates
If you are lighter or heavier than the average rider
and cannot set the proper ride height with altering
the correct spring pre-load, consider an optional
rear shock spring.
A spring that is too soft for your weight forces you
to add excessive spring pre-load to get the right
race sag and, as a result, the rear end of the
motorcycle is raised. This can cause the rear wheel
to unload too much in the air and top out as travel
rebounds. The rear end may top out from light
braking, or kick sideways over lips and square-
edged terrain. It may even top-out when you
dismount your CRF.
Because of the great absorption quality of the
shock bumper rubber, it may be difficult for you to
notice when your CRF’s suspension is bottoming.
Some riders may think the damping or perhaps the
leverage ratio is too harsh. In reality, the problem
is most likely insufficient spring pre-load or a
spring that is too soft. Either situation prevents
utilizing the full travel.
Keep in mind that a properly adjusted suspension
system may bottom slightly every few minutes at
full speed. Adjusting the suspension to avoid this
occasional bottoming may cost more in overall
suspension performance than it is worth.
A spring that is too stiff for your weight will not
allow the rear tire to hook up under acceleration
and will pass more bumps on to you.
