§ 02 / About this part
What it is
The RENTHAL SPROCKET F 520 13T SC, sprockets. Stocked by Iron Offroad, the UK MX hard parts specialist.
This front sprocket mounts to your gearbox countershaft to drive the final transmission. The self-cleaning mud grooves are essential for UK winter tracks, preventing debris build-up that stretches chains and wears teeth prematurely. Machined from case-hardened steel, it handles the high torque loads of modern four-strokes. Replace this part when teeth begin to hook or show visible thinning. Always check your output shaft seal for leaks during the swap. Ensure the locking washer is bent correctly over the nut to prevent loosening mid-moto.
