Rear Suspension - Honda CR250R 2004 Owner's Manual

4. SERVICE AND MAINTENANCE

REAR SUSPENSION

The swingarm is controlled by one hydraulic shock
absorber with an aluminum reservoir for oil and ni-
trogen gas pressure. The gas pressure in the reservoir
is contained within a rubber bladder.
The shock absorber's spring preload and damping
adjustments (compression and rebound) should be ad-
justed for the rider's weight and track conditions. (See
Section 6.)
•
The rear shock absorber assembly includes a
damper unit that contains high pressure nitrogen
gas. The instructions found in this owner's manual
are limited to adjustment of the shock assembly
only. Do not attempt to disassemble, disconnect or
service the damper unit; an explosion, causing
serious injury may result.
•
Puncture or exposure to flame may also result in an
explosion, causing serious injury.
•
Service or disposal should only be done by your
authorized Honda dealer or a qualified mechanic,
equipped with the proper tools, safety equipment
and the official Honda Service Manual.

NOTE:
•
When your CR is new, break it in for approximately
one hour with the standard suspension settings
before attempting to adjust the rear suspension.
•
Make all compression and rebound damping ad-
justments in specified increments or turns described
in page 53. (Adjusting two or more increments or
turns at a time may cause you to pass over the best
adjustment.) Test ride after each adjustment.
•
If the rear suspension is too stiff/soft, adjust it by
turning all the compression and rebound adjusters
according to the procedures described in page 70.
After adjusting the adjusters simultaneously, sus-
pension may be fine-tuned by turning one of the
compression or rebound damping adjusters in one-
click or in 1/12 turn increments.
•
If you have a problem finding an acceptable adjust-
ment, return to the standard position and begin
again.
Inspection
1. Check for a broken or collapsed spring.
2. Bounce the rear of the motorcycle up and down and
check for smooth suspension action.
3. Check the shock for a bent shaft or oil leaks.
