The Factory Links RWK-Y-146 rear wheel bearing kit is engineered for demanding off-road applications on Yamaha WR and YZ models. This kit features heavy-duty bearings pre-packed with high-performance marine-grade grease, which includes complex thickeners to render the bearing virtually waterproof and resistant to harsh environmental conditions. The enhanced grease filling, increased from 30% to 60%, ensures superior lubrication and protection in challenging terrains.
The bearings are sealed with nitrile butadiene rubber double-lip oil seals designed to prevent ingress of abrasives, moisture, and corrosive elements, thus extending the service life of the bearing assembly. A key innovation is the specially designed v-groove on the inner race, which improves water resistance and minimizes the risk of water intrusion during deep water crossings or muddy conditions. These features collectively provide unsurpassed rust and corrosion protection, ensuring reliable performance over time.
Factory Links' off-road specific design emphasizes durability and endurance, making these bearings an ideal replacement for aggressive riding environments. Precision-made to meet or exceed OEM standards, the RWK-Y-146 kit guarantees a smooth, quiet ride while safeguarding your motorcycle’s rear wheel assembly against the elements. Whether you're rebuilding or upgrading, this bearing kit offers robust, long-lasting performance tailored for Yamaha off-road bikes.
