Before installation
Refer to service manuals issued by the vehicle manufacturer and prepare tools necessary for the job. Please read the included instruction manual before installing.
Installation Notes:
Overtightening of suspension mount bolts will adversely affect the operation of the product.
After installation, please make sure that the suspension does not interfere with the peripheral parts (swing arm, muffler, drive chain, etc.)
Suspension swings to the back of the body as you stroke. Please make sure there is enough clearance around the frame and mount.
◆About the standard setting
YSS Suspension sets a spring rate based on a single passenger ride. If you have a large drop from the standard weight (65-75kg), or if you are running a tandem or circuit as the main one, we recommend replacing the option spring.
