§ 02 / About this part
What it is
The MOTO-MASTER CHAIN MM520GPX GK 120C, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
This 520-pitch O-ring chain is built for longevity in harsh off-road environments. Internal seals retain factory grease within the bushings to prevent grit from grinding down the pins. It features 120 links to accommodate most swingarm lengths and sprocket combinations. Check for stretch and side-play at regular service intervals to protect your engine cases and sprockets. Use a dedicated chain breaker for sizing and ensure the master link clip faces away from the direction of travel. This finish resists corrosion during wet winter sessions and pressure washing. Replace the chain if the rollers become loose or the O-rings perish.

§ 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.
