Shift Rail Countershaft for KTM 125-350 EXC SX XC 2003-2023 - 54834020000

This genuine OEM shift rail is a critical component of the motorcycle's internal shifting mechanism. It provides a smooth, precise guide for the shift forks to move along the countershaft, ensuring reliable gear transitions during operation. As an original equipment manufacturer part, it meets the exact specifications and tolerances required for your engine's transmission.

This part fits an extensive range of models including the KTM 125, 150, 250, 300, and 350 series (SX, SX-F, EXC, EXC-F, XC, XC-W) from 2003 to 2023. It is also compatible with Husqvarna TC, TE, FC, and FE models, as well as GasGas MC 125 and Freeride 250/350 models. Whether you ride a two-stroke or four-stroke machine, this rail is designed for broad cross-model application within the KTM group.

Constructed from high-strength hardened steel, this shift rail is built to withstand the constant friction and mechanical stress of gear changes. The polished surface finish reduces drag on the shift forks, which helps prevent missed shifts and premature wear on internal gearbox components. Replacing a worn or bent rail is essential for maintaining the integrity of your bike's shifting performance.

Installation requires splitting the engine cases, so it is recommended for experienced mechanics or professional service centers. During installation, ensure the rail is properly lubricated with fresh engine oil to facilitate smooth movement from the first start. Regular oil changes will help keep the shifting mechanism clean and extend the lifespan of this component.
