§ 02 / About this part
What it is
The RENTHAL SPROCKET F 525 17T, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
This component sits on the gearbox output shaft to drive your chain. It handles the highest torque loads in the drivetrain. Teeth eventually hook and thin out from constant grit and mud exposure. Inspect for hooking every few rides. Replace this alongside your chain and rear sprocket to prevent premature wear on new parts. Ensure the lock washer is bent or the circlip is fully seated during installation. Verify the specific torque setting for the countershaft nut in your workshop manual. This part is machined for a precise fit on your specific spline pattern.
