Factory Links OEM Series® Front Wheel Bearing Kits

Reference AB 25-1135

Engineered to deliver factory-level durability, precise fitment, and long-term reliability for off-road, enduro, and motocross motorcycles.

Designed to meet or exceed OEM specifications, each kit includes premium deep-groove ball bearings and Nitrile-Butadiene Rubber (NBR) double-lip oil seals—manufactured to strict dimensional tolerances to ensure proper hub alignment and smooth front wheel rotation.

Unlike generic aftermarket replacements, Factory Links bearings are packed with a heavy-duty marine-grade grease and a specialized thickener blend that improves water resistance and corrosion protection in harsh riding conditions.

Every kit includes all components required for a complete front wheel hub rebuild—helping eliminate play, restore smooth rotation, and extend service life in mud, water, sand, and extreme off-road environments.
