CAUSES POSSIBLE WORK
Unacceptable tightening Check the tightening torque of the upper and lower
collar. If the steering fails to turn smoothly even when
correctly tightened, inspect the bearing races and re-
place if they show signs of uneven wear.
HEAVY STEERING
EXCESSIVE STEERING PLAY
CAUSES POSSIBLE WORK
Excessive steering play Check the tightening torque of the upper and lower
collar. If the steering fails to turn smoothly even when
correctly tightened, inspect the bearing races and re-
place if they show signs of uneven wear.
NOISY SUSPENSION
CAUSES POSSIBLE
WORK
Front suspension components damaged Check for the absence of noise coming from the fork
during compression and rebound. If necessary, over-
haul the fork. Ensure the wheel spins freely and without
any noise; otherwise replace the wheel bearings.
Rear-suspension components damaged Check for the absence of noise coming from the fork
during compression and rebound. If necessary, check
the tightening torques on the swingarm and the absen-
ce of oxidations, or replace the shock-absorber. Ensure
the wheel spins freely and without any noise; otherwise
replace the final gearing train.
