The Sur Ron Light Bee uses a jackshaft in its two-stage drive system. The drive shaft acts as a reduction gear and has two bearings on each side.
Exposed to huge torque forces and constantly spinning at very high speed, the bearings wear out over time. If you feel an unusual grip, hear some noise or notice a play, it’s time for a change.
This kit contains four high quality NSK bearings and two seals so that you’re back with a brand new jackshaft!
