13.Rear Suspension
Position 1 is for light loads and smooth road conditions. Position
3 to 5 increase spring preload for stiffer rear suspension and
can be used when the scooters heavily loaded. Be certain to
adjust both shock absorbers to the same spring preload
positions.
Use a pin spanner to adjust the rear shock spring preload. The
shock absorbers are adjustable for pre-load. There are 5
settings. Position 1 is the softest and 5 is the stiffest.
Caution: Always adjust the shock absorber pre-load position in
sequence (1-2-3-4-5 or 5-4-3-2-1). Attempting to adjust directly
from 1 to 5 or 5 to 1 may damage the shock absorber.
(Pre-Load Standard Setting: Position 3)
