Designed for models manufactured between 2009 and 2020, this comprehensive repair kit provides everything needed to effectively rebuild your swingarm bearing assembly.

This kit features needle bearing shafts crafted from 52100 bearing steel, known for its durability and precision. Hardened and precision ground, these shafts ensure a snug fit and long service life.
