Rear shock absorber adjusters
The rear shock absorber has external adjusters that
enable you to adjust the setting to suit the load on the
motorcycle. The knob (1) located on the expansion
reservoir adjusts the compression damping.
The knob (3) located on the top connection holding
the shock absorber to the engine adjusts the rebound
damping.
Turn knob (1) clockwise to stiffen the damping, or
counter clockwise to soften it.
Turn knob (3) counter clockwise to stiffen the
damping, or clockwise to soften it.
The two ring nuts (2), located in the shock absorber
lower side, adjust the external spring preload.
To adjust the spring preload, loosen the bottom ring
nut. SCREWING or UNSCREWING the top ring nut
will INCREASE or DECREASE the preload.
Once the spring preload is set, tighten the bottom
ring nut.
STANDARD setting from the fully closed position:
- rebound: loosen adjuster (3) by 14 clicks (from
fully closed);
- compression: loosen adjuster (1) by 12 clicks
(from fully closed);
- spring preload: 0.55 in (14 mm).
