Moto-House MX Rear Wheel Bearing and Seal Kit — Yamaha YZ125 / YZ250 / YZ250F / YZ450F / WR 1998-2020

Product Description

Re-establish smooth power transfer and stable cornering precision with the premium Moto-House MX Rear Wheel Bearing and Seal Kit. Worn-out rear hub bearings introduce sloppy side-to-side wheel play, which degrades rear brake alignment, accelerates chain slider wear, and strips away rider cornering confidence. This heavy-duty kit completely refreshes your rear hub assembly, returning your rear suspension and drive line to factory tolerances to manage extreme track conditions.

Our heavy-duty assemblies are engineered with high-speed ball bearings manufactured to strict ABEC industry precision standards. Featuring an advanced dual or triple-lip sealing configuration backed by stainless steel garter springs, these bearings excel at retaining vital internal grease while aggressively keeping water, mud, and track silt out. Pre-packed with a premium marine-grade grease infused with rust and oxidation inhibitors, this kit offers superior protection against severe friction and premature component wear.

Frequently Asked Questions

Q: Does this kit package contain the bearings for both the left and right sides of the rear hub?
A: Yes, this Moto-House MX package comes completely outfitted with all the application-specific bearings and external dust seals needed to fully rebuild one rear wheel assembly.

Q: Are these wheel bearings ready to press into the hub directly from the box?
A: Yes, these bearings come pre-loaded with high-grade anti-oxidation grease and are fully sealed, meaning they require absolutely no pre-installation packing.

Q: Why are there metal springs inside the rubber dust seals?
A: Those are stainless steel garter springs. They exert continuous, even radial pressure on the rubber lips, keeping them firmly matched against the wheel spacers even during high-impact landings.

Expert Pro-Tip: When removing your old wheel bearings, gently heat the aluminum hub shell around the bearing bore with a propane torch or heat gun for a couple of minutes. Aluminum expands faster than the steel bearing outer race when heated, which allows the old worn assembly to tap out much easier and prevents scratching or gouging the soft aluminum inside your wheel hub.
