FACTORY LINKS REAR WHEEL BEARING KIT YAMAHA YZ 125/250 2021>

Factory links bearings use marine grease and special thickeners which allow them to be practically waterproof and at the same time perform optimally even under heavy stress conditions.
In order to prevent moisture from entering even in the harshest conditions, Factory links have gone from the traditional 30% grease fill to 60%.
The design specifically studied for the offroad world guarantees low torsional resistance and greater protection from external agents compared to a traditional 2RS industrial bearing.
