LUBRICATION POINTS
Proper lubrication is important for
smooth operation and long life of each
working part of your motorcycle and
also for safe riding. It is a good practice
to lubricate the motorcycle after a long
rough ride and after getting in snow,
wet, mud or after washing it. Major
lubrication points are indicated.
! WARNING !
Lubricant cannot spill over brake
disk or tires, otherwise grip and
braking capacity are considerably
reduced and rider may lose
motorcycle control.
CHECKING AND ADJUSTING
STEERING HEAD BEARINGS (*)
Check steering head bearings for play
periodically. For check, place
motorcycle on a stand so that the front
wheel is off the ground. Try to move the
fork forward and backward.
Check if handlebar rotates freely.
Check if control cables don’t interfere
with handlebar rotation.
If handlebar rotates in a not even way,
grips or has vertical movement, check
and adjust steering stem bearings.
Note: If you press brake lever and
compress several times front
suspension, while with left hand fingers
positioned between adjusting nut and
steering stem, may be detected any
bearings clearance.
For readjusting, loosen top nut (2) and
the two bolts (1) of the top triple clamp
and turn steering stem bolt (3)
clockwise until there is no more play.
Don’t tighten the steering stem bolt (3)
all the way; otherwise the bearings will
be damaged. With a plastic hammer,
lightly rap on the triple clamp to relief
tension and retighten the bolts. Then
tight top nut (2) and the top triple clamp
screws (1).
Steering head bearings should be
greased at least once a year.
! WARNING !
If steering head bearings are not
adjusted to be free of play or too
tight, the motorcycle will become
unstable and can get out of control.
Also they might be permanently
damaged.
