§ 02 / About this part

What it is

The RENTHAL SPROCKET R 520 51T GN SC TWIN, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

Combining a lightweight aluminium core with a hardened steel outer ring, this sprocket is built for the demands of competitive racing. It mounts to the rear hub and offers significantly more service life than a standard aluminium part. The 51-tooth sizing provides a slight increase in acceleration, making it effective for technical tracks and heavy soil. Look for hooking or side-wear on the teeth as indicators that a replacement is necessary. Always install with new fasteners and ensure the chain is adjusted correctly to prevent premature wear on the new teeth.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron Stable — a UK shop for motocross, enduro, and trail-bike hard parts. Every fitment lives on the site, listed against KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is the data: fully enriched fitment so you find the right part for your bike quickly and get it fitted accurately. 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 and e-moto only. We operate from our storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. The business has a rich motorcycle history across multiple moto brands — the photos show where we came from — and recently pivoted into hard parts and online retail.
