Troubleshooting

Below are a few examples of how to adjust 
for the most common road holding prob-
lems in Road Racing driving.

1.
The front wheel “chatters” entering a 
corner, the problem goes away, as soon as 
you let the brakes off, or when you get on 
the power.

•     This is caused by the fact that the fork is working
       too low in the travel and reaches the progressive,
       hard part at the end of the travel.

•     Put on more pre-load.

•     Change to a harder spring.

•     If a lot of stroke remains after riding, drop the oil
       level. See oil level chart.

•     Make sure the front forks have no friction.

•     Rear ride height is to high, too much rear spring
       pre-load.

•     Lower the rear end by taking off pre-loadfrom rear
       shock spring.

2.
The front wheel is jumping during the last 
part of braking.
 

•     If a lot of stroke remains, the oil level is too high. 
Lower the oil level.

•     If the fork is bottoming, put in harder springs and 
keep the oil level.

3.
The front end feels unpredictable and un-
safe in the middle of the corner (between 
braking and getting on power).

•    Not enough rebound damping. Put on more 
      damping.

•     Too much rebound damping. If it at the same time
       feels harsh, take off some rebound damping.

•     Too much compression damping. Also gives a
       harsh feeling. Take off some compression 
       damping.

4.
The front end loses grip coming out of a 
corner.

•     Not enough rebound damping. Put on some more
       rebound damping.

•     Too much pre-load. Take off some pre-load.

•     Rear end is too soft. Put on a harder rear spring.

•     Front end is too high. Lower the front end by
       pulling the fork legs through the triple clamps.

As mentioned in the beginning, the whole 
bike setup affects the front forks. Try to 
understand the feelings and work step by 
step.
