§ 02 / About this part
What it is
The RENTHAL SPROCKET F 520 14T UL, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
This part sits on the engine output shaft to drive your final transmission. Machined from case-hardened steel, it handles the high torque and abrasive grit typical of UK tracks. Replace it when you notice teeth hooking or during a full drivetrain refresh. A worn front unit accelerates chain stretch and ruins your rear teeth. Ensure the splines are clean and lightly greased before sliding the unit onto the shaft. Check your lock washer or circlip for tension during install. This is a direct OEM replacement for your specific spline configuration.
