Rear Wheel Axle Nut M20x1.5 for KTM, Husqvarna & GasGas 1994-2025 - 50310099000

This genuine OEM hexagon nut is a critical component for securing the rear wheel axle on a wide variety of motorcycles. Specifically designed with an M20x1.5 thread, it ensures the rear wheel remains properly torqued and aligned during intense riding conditions. As an original equipment manufacturer part, it guarantees a perfect fit and meets the high-strength standards required for off-road and street performance.

This part is compatible with an extensive range of models including the KTM 85 SX, 125-530 EXC, SX, and XC-W series, as well as the 640 Adventure from 1994 to 2025. It also fits Husqvarna models such as the TC 85, TE 125-300, and FE 250-501, alongside GasGas MC 85, EC 250-350, and EX 250-300 models. Additionally, it is used on specialized bikes like the KTM Freeride E-XC, RC4 R, and various LC4-based machines.

Constructed from high-grade steel, this nut is built to withstand the high torque loads and vibrations common in motocross and enduro racing. The flanged design helps distribute pressure evenly across the swingarm or chain adjuster blocks, preventing loosening over time. Its corrosion-resistant finish ensures longevity even when exposed to mud, water, and harsh cleaning chemicals.

When installing this rear axle nut, always refer to your motorcycle's service manual for the specific torque settings. It is recommended to inspect the nut for thread wear or rounding of the hex head during every tire change or chain adjustment. Replacing a worn or damaged nut is essential for maintaining the safety and structural integrity of your bike's rear end.
