The spring pre-load adjuster ( ) has

Positions 1 to 4: for a light load and
smooth road conditions.
Position 5: standard position.
Positions 6 to 9: for when the motorcycle
is more heavily loaded. (Also increase
spring pre-load for stiffer rear suspension.)
Always adjust the shock absorber position
in sequence (1-2-3-4-5-6-7-8-9 or 9-8-7-6-
