Adjusting the rear shock absorber
The rear shock absorber used on this motorcycle has rebound (return), compression and spring preload
adjustment.
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.
The shock absorber is adjusted by electric impulses sent by the instrument panel to the adjusters inside the shock
absorber body.
Warning
The shock absorber is filled with gas under pressure and may cause severe damage if taken apart by someone
who is unskilled.
