Extended Product Information

FAQs

Does this fit my 2010 KTM?

No, this specific part is designed for models spanning 2013-2022. Please check your specific axle thread requirements.

Is the M25 x 1.5 measurement for the diameter or length?

The M25 refers to the 25mm nominal diameter of the thread, and 1.5 refers to the thread pitch in millimeters.

Can I use this on a street bike?

This component is designed specifically for the high-performance demands of motocross and off-road motorcycles.

Does it come with a washer?

The product is the axle nut itself; ensure your existing axle assembly washer is in good condition before re-installation.

What if my bike is not listed in the compatibility list?

If your bike is not listed, do not assume fitment. Always cross-reference the thread pitch and diameter with your motorcycle owner's manual.

Troubleshooting

Nut feels tight or difficult to thread on

Stop immediately. Clean the axle threads with a wire brush to remove debris, and ensure the nut is perfectly square to the axle.

Nut backs off during riding

Verify that the torque applied matches the factory specification and ensure the safety locking mechanism or cotter pin (if applicable to your specific axle setup) is correctly utilized.
