Important to know

Before purchasing or installing shocks with a different length than the OEM, ensure sufficient wheel travel to avoid clearance issues such as swingarm/axle to exhaust contact or chain/belt guard and tire contact. Heavy Duty (HD) applications are recommended for bikes operated at or near maximum load rating over 50% of the time.
