§ 02 / About this part

What it is

The RENTHAL SPROCKET R 520 48T RD SC TWIN, sprockets. Stocked by Iron Offroad, the UK MX hard parts specialist.

This rear drive component uses a dual-material design. The outer steel ring handles the chain torque and resists tooth wear. The inner aluminium section reduces unsprung weight at the hub. Replace this when teeth begin to hook or show visible thinning. Always fit a new chain and front sprocket at the same time to prevent premature wear on the new teeth. Check your chain tension after the first heat cycle. This part is built for high-hour enduro use and gritty MX conditions where standard aluminium rings wear too quickly.

§ 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.
