§ 02 / About this part

What it is

The RENTHAL SPROCK R 420 48T SI UL SC, sprockets. 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.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron stable — this is a UK shop for motocross, enduro, and trail-bike hard parts. All fitments live on the site, and listed against MX models KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is in the data, fully enriched to assist with accurate fitting and finding the right part for your bike quickly and easily. Brands you'd find on a paddock workbench; pads, sprockets, plastics, fork seals, cables, gaskets, bars, the things that actually wear out. Road-bike kit, scooter parts, and quad gear sit elsewhere. Dirt & e-moto only. We operate from our huge storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. We have a RICH motorcycle history with multiple moto brands the images showing where we came from and our history, the business recently pivoted into hard parts and online retail.
