Description
Description
This genuine OEM M8 Hex Collar Nut is a high-quality fastener designed specifically for securing the cylinder to the engine crankcase. As a critical component of the engine assembly, it provides the necessary clamping force to maintain a reliable seal and prevent vacuum leaks. Using original factory parts ensures that the material hardness and thread precision meet the exact requirements of your high-performance engine.
This versatile part fits a wide array of motorcycles, including KTM 125 SX, 125 EXC, 150 SX, 150 XC-W, and 200 EXC models spanning from 1997 to 2026. It is also the correct fitment for Husqvarna TC 125, TE 125, TE 150, and TX 125 models, along with GasGas MC 125 and EC 125 bikes. It covers everything from early 200cc models to the latest fuel-injected two-stroke machines.
The integrated flange design acts as a built-in washer, distributing load evenly to protect the cylinder surface from marring. With a 12mm hex head, it allows for precise torquing even in the tight spaces around the cylinder base. The durable finish is engineered to withstand the extreme heat cycles and vibrations common in off-road racing environments.
For the best results, always use a calibrated torque wrench during installation to meet factory specifications. Replacing these nuts during a top-end service is a cost-effective way to ensure your engine remains reliable and leak-free.
