Product Overview
This is a brand new, genuine Yamaha factory replacement swingarm pivot collar. This hardened steel spacer acts as the inner race for your swingarm needle bearings. Over time, moisture and grit penetrate the pivot seals, causing this collar to develop "grooves" or pitting. Once the surface is compromised, your rear suspension will have lateral "slop," leading to poor handling and accelerated bearing wear. Replacing a worn collar with this genuine Yamaha part restores factory-spec tolerances and smooth suspension travel.
Why Choose Genuine Yamaha?
Suspension pivot points operate under extreme pressure. Aftermarket collars are often made of softer steel that "grooves" quickly under load. This genuine Yamaha part is manufactured from high-carbon, hardened Japanese steel, precision-ground to a mirror finish to provide the lowest possible friction and maximum service life.
