Front Suspension Adjustments - Honda CR125R 2006 Owner's Manual

Front Suspension Adjustments

The front suspension can be adjusted for the
rider's weight and riding conditions by using one
or more of the following methods:
• Oil volume — The effects of higher or lower
fork oil level are only felt during the final 3.9
in (100 mm) of fork travel.
• Compression damping — Turning the
compression damping screw adjusts how
quickly the fork compresses.
• Rebound damping — Turning the rebound
damping screw adjusts how quickly the fork
extends.
• Fork springs — Optional springs are
available in softer and stiffer types than the
standard rate. (page 127)

Front Suspension Air Pressure
Air is an unstable gas which builds up pressure
as it is worked (such as in a fork). Air pressure
acts as a progressive spring and affects the entire
range of fork travel. This means the fork action
on your CR will get stiffer during a race. For
this reason, release built-up air pressure in the
fork legs between motos. Be sure the fork is
fully extended with the front tire off the ground
when you release the pressure.
The standard air pressure is 0 psi (0 kPa, 0
kgf/cm 2 ). You may relieve accumulated air
pressure in the fork legs by using the pressure
release screws. The front wheel should be off the
ground before you release the pressure.
The air pressure should be adjusted according to
the altitude and outside temperature.
1. Place an optional workstand under the engine,
so that the front wheel is off the ground.
Do not adjust air pressure with the front wheel
on the ground as this will give false pressure
readings.
2. Remove the pressure release screws (1).
3. Check that the O-ring (2) is in good condition.
4. Install the pressure release screws to the
specified torque:
0.9 lbf·ft (1.2 N·m, 0.1 kgf·m)
