Additional Maintenance Procedures - Honda CRF450X Owner's Manual

Refer to Safety Precautions on page 25.
Steering Head Bearing Inspection
1. With your CRF on a box or optional
workstand (front wheel elevated), turn the
handlebar to the right and left to check for
roughness in the steering head bearings.
2. Stand in front of your CRF, grab the fork (at
the axle), look at the steering head, and push
the fork in and out (toward the engine) to
check for play in the steering head bearings.
If any roughness or play is felt, but you do
not see any movement in the steering head,
the fork bushings may be worn. Refer to the
Honda Shop Manual for replacement or
adjustment procedures, or see your Honda
dealer.

Control Cables
Periodically, disconnect the throttle, clutch and

Be sure the throttle returns freely from fully open
to fully closed automatically, in all steering
