The Warp 9 Racing Yamaha 20mm Front Bearing Kit is a complete rebuild kit designed to refresh your front wheel bearing and seal setup on select Yamaha YZ and WR models. It includes two 6904 bearings (37mmx20mm), two 26-37-7 seals, and a distance tube, providing the key wear components needed when servicing a 20mm front hub. Replacing worn bearings and seals helps maintain smooth wheel rotation and supports consistent handling by reducing play and contamination. Fitment includes a wide range of Yamaha off-road models spanning multiple year ranges, including YZ125, YZ250, YZ250F, YZ450F, and WR models as listed below.
This kit include the following: 2- 6904 bearings (37mmx20mm), 2- 26-37-7 seals, and a Distance Tube. Together, these components address the common wear items involved in a front bearing service so you can rebuild the front wheel bearing/seal stack with matching parts in one kit.
The kit is based around 6904 bearings sized 37mmx20mm, matching a 20mm front application as specified in the product name. Using the correct bearing size is critical for proper fit and support of the front wheel/hub assembly on the compatible Yamaha models listed.
