§ 02 / About this part

What it is

The RENTHAL SPROCKET F 525 17T UL, sprockets. Stocked by Iron Offroad, the UK MX hard parts specialist.

This large-diameter countershaft sprocket is designed for higher top-end speeds on faster tracks or road-link sections. It mounts directly to the gearbox output shaft and features mud-clearing grooves to maintain chain alignment in soft terrain. Inspect the teeth regularly for hooking or thinning, as a worn front sprocket will rapidly ruin a new chain. When fitting, ensure the splines are clean and the retaining nut is torqued to OEM specifications. This steel component offers a direct replacement for your factory gearing while providing better debris clearance than standard parts.

§ 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.
