Yamaha MT-09 2021 - ADJUSTING the FRONT FORK LEGS (for MTN890 D)

3-23
PERIODIC MAINTENANCE
TIP
Although the total number of clicks of a damping
force adjusting mechanism may not exactly
match the above specifications due to small dif-
ferences in production, the actual number of
clicks always represents the entire adjusting
range. To obtain a precise adjustment, it would
be advisable to check the number of clicks of
each damping force adjusting mechanism and
to modify the specifications as necessary.
