Riding experience
Beginner: Soft spring with rebound.
Experienced: Harder spring.
Rider's weight
Heavy: Hard spring.
Light: Soft spring.
Type of racing circuit
- Many corners:
Lower the front end slightly (Raise the fork tubes 5 mm).This increases
agility.
- Fast course with many jumps:
Raise the fornt end slightly (Lower the fork tubes 5 mm).
- Deep potholes or sandy ground:
Raise the front end slightly to gain stability.
After making such preliminary adjustments, begin the actual on-track
testing and evaluation.
CAUTION
1- Make changes one step at a time.
2- Make sure the rider is consistent in this evaluation.
3- A change in the front suspension requires a change in the rear,
and vice versa.
Front and rear compatibility:
Use this procedure to determine if the suspension is balanced. Place
the motorcycle upright. While standing next to the right side of the
motorcycle, hold the front brake and press the rear brake pedal firmly.
If the motorcycle maintains its level attitude as the suspension is
compressed, the spring rates are well balanced. Sit astride the
motorcycle and take a riding posture. Next check to see that the
motorcycle is in a horizontal 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 terrain and the
rider´s preferences.
Does the motorcycle skids when driving down hill or when
accelerating out of a curve?
Front fork is too soft.
1. Increase the compression or rebound damping.
2. Increase the oil level 10 mm.
3. Use a harder spring, or increase spring preload.
Does the front end tends to turn inward?
Front fork is too soft.
1. Increase the compression or rebound damping.
2. Increase the oil level 10 mm.
Does the front end slips when entering in a curve?
1. Decrease the compression or rebound damping.
2. Bleed air trapped in the fork.
3. Decrease the oil level 10-20 mm.
4. Use a softer spring.
