Description
The top end bearing is critical to your KTM 65 SX’s reliability under sustained high RPM operation. A worn or substandard bearing introduces friction, accelerates wear on adjacent components, and compromises the smooth power delivery your engine needs on the track or trail. The Wiseco B1042 delivers precision engineering and durability that keeps your engine running at peak efficiency through extended racing seasons.
