Boss Bearing 41-4001B Rear Wheel Bearing Kit KTM & Husqvarna

Keep your KTM or Husqvarna rolling smooth with the Boss Bearing 41-4001B Rear Wheel Bearing Kit. One kit covers a wide range of KTM Adventure, Duke, Enduro, Supermoto, SMC, and RC 8 models, plus Husqvarna 701, Norden, Svartpilen, and Vitpilen models, across model years 2005 to 2026.

Worn rear wheel bearings cause wheel play, hum, vibration, and uneven tire wear. On big-torque twins and singles like these, that wear builds fast, especially with hard riding, loaded touring, or wet and dirty conditions. Replacing them restores smooth, stable rear wheel rotation and protects your hub and axle.

Fitment spans many models and years, so check the chart below to confirm compatibility with your bike.
