This genuine OEM Stop Disc is a critical component for the transmission assembly of your motorcycle. It acts as a precision thrust washer on the main shaft, ensuring correct spacing between gears and reducing axial friction during operation. Using original factory parts maintains the integrity of your gearbox and ensures smooth, reliable shifting performance.

This wide-ranging compatibility makes it a versatile spare part for many 250cc four-stroke engines.

Manufactured from high-grade hardened steel, this stop disc is built to withstand the intense heat and pressure found inside the crankcase. Its durable construction prevents premature wear and helps maintain the alignment of the transmission gears. Replacing worn or damaged shims is essential to prevent excessive shaft play and costly internal damage.

When performing maintenance or a full engine rebuild, always inspect the transmission washers for signs of scoring or thinning. It is best practice to replace these components whenever the transmission is serviced to ensure the longevity of your drivetrain.
