Pinion for Yamaha - ratio 15/520 - Superpinion 086/15T

A valid alternative to every pinion

The shapes of the original pinion have been reset to allow him to take up All the teeth of the secondary transmission shaft

To pursue the goal, the type of lock was also changed, which does not take place anymore but laterally.

SUPERPINION, patented pinion:

• Prevents the wire wear also with intensive use (off-road, racing)
• Overcomes the damage created by old sprockets, postpone the onerous replacement of the tree in the long term
• Being more stable, promotes alignment constant with chain and crown, making the movement of the system more smooth and prolonging his life cycle

In each package the locking plates and screws are included
