Using original parts ensures that your engine maintains its factory tolerances and long-term reliability.

This kit is compatible with a wide range of 450cc and 500cc models from 2015 to 2026. It fits KTM 450 SX-F, XC-F, EXC-F, and 500 EXC-F/XCF-W models.

The NJ207 cylinder roller bearing is engineered to handle the high RPMs and heavy loads typical of motocross and enduro riding. The included shims allow for precise adjustment of crankshaft end play, which is critical for preventing premature wear on engine cases and internal components. These components are manufactured to meet strict engineering standards for maximum durability in extreme conditions.

Replacing crankshaft bearings is a technical task that requires splitting the engine cases. We recommend using professional tools and following the manufacturer's torque specifications during reassembly to ensure optimal performance. Regularly inspecting your bottom end during major service intervals can prevent catastrophic engine failure.
