OEM Transmission Stop Disk for KTM, Husqvarna & GasGas 1997-2026 - 79333043000

This genuine OEM transmission stop disk is a critical component for maintaining proper spacing and alignment within your motorcycle's gearbox. It is designed to sit on the transmission shafts, ensuring smooth gear transitions and preventing excessive lateral movement of gears during operation. As an authentic factory part, it meets the exact tolerances required for reliable engine performance.

This stop disk features extensive compatibility across KTM, Husqvarna, and GasGas lineups from 1997 through 2026. It fits a wide variety of displacements including 125, 150, 200, 250, 300, 350, and 450cc models. Specifically, it is used in KTM SX, SX-F, EXC, and XC models; Husqvarna TC, FC, TE, and FE models; and GasGas MC and EX series motorcycles.

Manufactured from high-grade materials, this stop disk is built to withstand the high heat and friction found inside a high-performance transmission. Using original parts during a gearbox rebuild is essential to ensure that gear engagement remains precise and to prevent premature wear on the main and countershaft assemblies.

When performing maintenance or a full engine overhaul, always inspect your thrust washers and stop disks for signs of thinning or surface scoring. Replacing these small but vital components can prevent costly transmission failures and ensure your bike stays in peak racing condition.
