Rear Suspension Adjustments
The suspension on “entry level” pit bikes uses a
coilover shock absorber with adjustable preload.
This shock absorber will have a notched collar that
allows the rider to adjust the rear suspension from
soft to rm.
The simplest truly adjustable rear suspension uses
a one-way or single adjustable coilover shock and
allows the rider to reset the rebound from “faster”
or “slower”. This is usually done at the bottom
(swing arm end) of the shock with a either a hand-
turned knob or wheel. “Faster” rebound allows the
shock to extend or open more quickly after being
compressed (closed); “slower” retards the shock’s
extension after being compressed.
Two-way or double-adjustable coilover shocks
have separate adjustments for both compression
and rebound. Rebound is usually reset in the same
manner as a one-way (single-adjustable) shock.
Compression is generally reset at the top of a two-
way shock. Most two-way shocks use a pressurized
inert gas like nitrogen as the compression adjusting
medium, and adjustments are made from “soft” to
“hard” using a knob on the pressurized gas res-
ervoir that is externally mounted on the top of the
shock.
