§ 02 / About this part
What it is
The RENTHAL SPROCK R 420 46T SI UL SC, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
This ultra-light rear sprocket features self-cleaning mud grooves to prevent dirt build-up between the teeth. It mounts to the rear hub and uses a 420 pitch for small-bore machines. The aluminium construction reduces rotating mass for improved acceleration and rear-end feel. Replace the sprocket if the teeth show hooking or thinning to avoid chain damage. Always install a new chain with a fresh sprocket to maintain drive train integrity. Use new sprocket bolts and threadlock during fitment. This is a performance upgrade for junior racing in muddy UK conditions.
