Checking the front fork
The condition and operation of the
front fork must be checked as follows
at the intervals specified in the
periodic maintenance and lubrication
chart.
To check the condition
Check the inner tubes for scratches,
damage and excessive oil leakage.
To check the operation
1. Place the motorcycle on a level
surface and hold it in an upright
position. WARNING! To avoid in-
jury, securely support the vehi-
cle so there is no danger of it
falling over.
2. While applying the front brake,
push down hard on the handle-
bars several times to check if the
front fork compresses and re-
bounds smoothly.

pair it.
