Riding experience
Beginner Softer: spring with more rebound damping.
Experienced: Harder spring.
Rider's weight
Heavy: Harder spring.
Light: Softer spring.
Type of course
- Many corners:
Lower the front end slightly (increase the fork tube height 5mm).This
quickes steering and turning ability.
- Fast course with many jumps:
Raise the fornt end slightly (decrease the front tube height 5 mm).
- Deep whoops, or sandy ground:
Raise the front end slightly to gain stability.
fter making such preliminary adjustments, begin the actual on-track
testing and evaluation.
CAUTION
1- Always make changes in small increments.
2-Make sure the rider is consistent in this evaluation of improper
suspension performance.
3- A change in the front suspension might require a change in the
rear, and vise versa.
Front and rear compability:
Use this procedure to determine if the suspension is balanced
reasonably well: Hold the bike upright (retract the side stand). While
standing next to the machine, lightly pull on the front brake, place
one foot on the footpeg closest to you, and push down hard. If the
bike maintains its level attitude as the suspension is compressed,
the spring rates are well balanced. Sit astride the bike and take a
riding posture. Next check to see that the bike is in a horitzontal
position. If one end drops noticeably more than the other, the front
and rear are not compatible and must be readjusted to achieve a
better balance.
This is one of the most effective adjustment procedures but suspension
settings will vary depending on the conditions at the track and the
rider´s preferences.
Front end seaching during down hill or during acceleration out
of corner:
Front fork is too soft.
1. Increase the compression damping or rebound damping.
2. Increase the oil level 10 mm.
3. Use alternate harder sping, or increase spring preload.
Front end ¨knifes¨or oversteers in turns: (front end tends to
turn inward):
Front fork is too soft.
1. Increase the compression damping or rebound damping.
2. Increase the oil level 10 mm.
Front end pushes or ¨washes out¨in turns:
1. Decrease the compression damping or rebound damping.
2. Release the air at the fork tubes.
3. Decrease oil level 10-20 mm.
4. Use softer spring.
