§ 02 / About this part

What it is

The RENTHAL SPROCKET F 520 16T UL, sprockets. Stocked by Iron Offroad, the UK MX hard parts specialist.

This ultralight countershaft sprocket sits on the gearbox output shaft to drive your chain. The drilled design reduces rotating mass without compromising strength. It is a critical wear item in your drivetrain. Replace it when the teeth begin to hook or thin out. Always fit a new front sprocket when installing a new chain to prevent premature wear. This steel component is machined to precise tolerances for an exact fit on your bike's splines. Ensure the locking washer or circlip is seated correctly during installation. Check your workshop manual for the specific torque setting on the countershaft nut.

§ 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.
