2. SUSPENSION TUNE-UP
This adjustment is very critical because if an improperly tuned suspension will
keep even the best rider from attaining the full benefit of his machine´s ability.
Check the suspension in accordance to the rider and the terrain conditions:
- If the motorcycle is new, break-in the suspension with at least one hour of
riding before making any setting evaluations or changes.
- The three factors which must be considered are rider’s weight, rider’s abil-
ity, and terrain conditions (additional in fl uences include the rider´s style
and position on the motorcycle).
- If you have a problem, test by changing your riding posture or position so
it can be deduced.
- Adjust the suspension to match the rider´s strong points. If he is fast
through the corners, adjust the suspension to allow fast cornering.
- Make setting changes in small increments; a little bit goes a long way, and
it is very easy to overadjust a setting.
- The front and rear suspension should be balanced; when one is changed,
the other might need to be changed similarly.
- When evaluating suspension performance the rider must make every
e ff ort to ride consistently and recognizing the e ff ects of his input; such
things as changes in rider position and increasing fatigue may lead to in-
correct judgments about necessary setting adjustments.
- When the proper settings have been determined for a particular terrain,
the settings should be written down for later reference when returning to
the same type of terrain.
- Before making any changes and also every 5 fi ll-ups, lubricate the swin-
garm bearings, torque rod, linkages and O-rings, this precaution will pre-
vent excesive friction that can a ff ect the suspension performance.
Front fork
The oil level is adjustable. A change in the oil level will not a ff ect the lower
part of travel, but it will have an a ff ect on the upper part of travel:
- When the oil level is raised:
The spring e ff ects become more progressive, and the front fork action
feels harder at the end of travel.
If the front suspension is making jounce stops, raise the oil level 10 mm.
This increase will provoke a change in upper part of travel of the spring.
- When the oil level is lowered:
The spring e ff ects are less progressive, and the front fork action does not
become hard at the end of travel.
- Change the oil level correctly and the fork will work more at the end of
fork travel.
Oil level adjustment
Adjust the front fork oil level (refer to the maintenance chart).
