The Yamaha 25mm Rear Direct Drive Hub Wheel Bearing Kit from Warp 9 Racing is a complete rebuild kit designed to refresh the rear direct drive hub’s wheel bearing and sealing system on select Yamaha off-road models. It includes three 6905 bearings in 42mmx25mm size, two 32-43-7 seals, and the correct distance tube to restore proper spacing and support inside the hub. This kit is intended for WR and YZ fitments listed below, covering model-year ranges from 09–24 and 24–current as specified, making it a straightforward way to replace worn bearings and seals with the correct components in one package.
This kit include the following key hub wear items in one package: 3-6905 bearings (42mmx25mm), 2- 32-43-7 seals, and a distance tube. Replacing bearings, seals, and the distance tube together helps restore correct internal spacing and sealing when servicing the rear direct drive hub.
Built around 6905 bearings sized 42mmx25mm, this kit is for Yamaha applications specified as 25mm. Matching the correct bearing size is critical for proper fit in the hub and for long-term durability when the rear wheel is under load.
Specified fitment includes WR250F 25–current, WR450F 24–current, YZ250F 09–24, YZ450F 09–24, and YZ450FX 24–current. Use the model and year range listed here to confirm compatibility before installation.
