Suspension
Adjustment
:
1. Front forks
1.1. Fork oil
1.1.1. Oil type
1.1.1.1. Heavier weight oil – more damping – slower responding
1.1.1.2. Lighter weight oil – less damping – quicker responding
1.1.2. Oil quantity / level
1.1.2.1. Greater
quantity / higher level – greater bottoming resistance,
stiffer near the end of the travel.
1.1.2.2. Smaller quantity / lower level – less bottoming resistance, less
stiff near the end of the travel.
1.2. Fork spring
1.2.1. Stiffer spring (higher spring rate) – stiffer throughout the travel.
1.2.2. Less stiff spring (lower spring rate) – less stiff throughout the travel.
1.3. Gas pressure – always bleed off any pressure.
1.4. Fork height
1.4.1. Rise in clamps for quicker turning.
1.4.2. Lower in clamps for improved straight line stability.
2. Rear shock
2.1. Preload adjustment
2.1.1. More preload (greater distance) – less race sag.
2.1.2. Less preload (smaller distance) – more race sag.
2.2. Shock spring
2.2.1. Stiffer spring – stiffer throughout the travel.
2.2.2. Less stiff spring – less stiff throughout the travel.
2.3. Compression damping
2.3.1. Harder (more damping, slower) – adds resistance to the suspension
motion when the suspension is compressing.
2.3.2. Softer (less damping, quicker) – reduces resistance to the
suspension motion when the suspension is compressing.
2.4. Rebound damping
2.4.1. Harder (more damping, slower) – adds resistance to the suspension
motion when the suspension is returning to full length.
2.4.2. Softer (less damping, quicker) - reduces resistance to the suspension
motion when the suspension is returning to full length
Front Forks Bottoming Too Frequently
Fork oil level
If the front forks bottom harshly more than a couple of times per lap and the fork
springs are proper for the weight of rider (as detailed above), try raising the fork oil
level in increments of 10mm. Raising the fork oil level, reduces the air volume, and
increases the stiffness of the forks late in the travel, thus adding a progressive’
feel.
Front forks feel too stiff over small bumps.
Fork oil weight
If the forks feel too stiff over small bumps try decreasing the weight (increasing the
viscosity) of the fork oil.
