Description
The top end bearing is critical to your KTM 125 SX’s reliability—a worn or damaged bearing will compromise piston rod movement and accelerate wear across your entire top end. This Wossner bearing is engineered to OEM specifications with tight tolerances, ensuring smooth operation under the extreme temperatures and loads that come with racing or hard trail riding. Replace it during a top-end rebuild to restore performance and extend engine life.
