§ 02 / About this part

What it is

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

This dual-material rear sprocket combines an aluminium core with a steel outer tooth section. It sits on the rear hub and offers a balance between reduced unsprung weight and long-term durability. The steel teeth are essential for riders tackling sandy or muddy terrain where aluminium wears prematurely. A 48-tooth configuration is suited for faster tracks where higher top speeds are required. When fitting, check your chain tension and inspect your front sprocket for wear. Use a torque wrench on all mounting bolts to meet OEM specifications and prevent loosening.

§ 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.
