Description
The top end bearing on your KTM 65 SX takes a beating during aggressive riding and racing—worn bearings lead to increased friction, excessive play, and premature piston wear. Wossner’s precision-engineered top end bearing is built to OEM specifications with tight tolerances and durable construction, ensuring your small-displacement machine maintains consistent performance lap after lap. Replace this critical component before failure occurs, and you’ll notice smoother power delivery and extended engine life.
