§ 02 / About this part

What it is

The RENTHAL SPROCKET REAR 520 51T PURPLE U, sprockets. Stocked by Iron Offroad, the UK MX hard parts specialist.

This drive component sits on your hub to drive the final transmission. CNC-machined from 7075 T6 aluminium, it reduces unsprung weight for better suspension response. Replace this part when the teeth show visible hooking or thinning. Mud grooves are machined into the tooth base to prevent dirt build-up under the chain. This unit uses a model-specific bolt pattern for a direct fit. Always check your chain tension and alignment after fitting. Use new mounting bolts to ensure a secure fit. This anodised finish stands up to trail debris. Match it with a new chain for even wear.

§ 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.
