Rear Shock Absorber Adjusters - Monster 659 Owner's Manual

Rear shock absorber adjusters

E
The shock absorber has external adjusters that enable you to
adapt the set up to suit the load conditions. Adjuster (1),
located on the left-hand side at the point at which the top of
the shock absorber is fixed to the rear sub-frame, controls
rebound damping. Turn the adjuster (1) clockwise to increase
damping H; or anticlockwise to reduce damping S.
The two nuts (2) on the lower part of the shock absorber
serve to adjust the preload on the external spring.
To change spring preload, turn the upper ring nut. Then
tighten or slacken the lower ring nut to increase or decrease
spring preload.
STANDARD setting from fully closed position (clockwise):
- unscrew adjuster (1) by 8 clicks from Max (fully closed).
Spring preload: 20 mm from Min (fully unloaded).
STANDARD length of the preloaded spring on the shock
absorber with the rear wheel raised off the ground:
150±1 mm.
Warning
When adjusting the spring preload, do not exceed a
spring length of 181 mm to avoid damaging the swingarm.
Warning
Use a specific pin wrench to turn the preload adjusting
nut. Be careful when turning the nut with the wrench, as the
pin may slip out of the ring nut recess and you may hurt your
hand hitting motorcycle parts.

Warning
The shock absorber is filled with gas under pressure
and may cause severe damage if taken apart by unskilled
persons.
When carrying a passenger and luggage, set the rear shock
absorber spring to proper preload to improve motorcycle
handling and keep safe clearance from the ground. You may
find that rebound damping needs adjusting as well.
