Legends Clutch Boss Nut Locking Ring for Yamaha FJ1200 XJ1250

Clutch Boss Nut Locking Ring for FJ1200 / XJ1250.

We recommend that you replace this piece with every 1200/1250 Legends Race Car clutch replacement. If one of the tabs break off, the nut will back off, causing the oil pump to become disengaged from the clutch assembly resulting in oil starvation and a blown engine.

An ounce of prevention is worth a pound of cure.
