§ 02 / About this part

What it is

The MOTO-MASTER SM RACE KIT: 320mm FLOATING FLAME, BRAKE PADS/LINE,4 PISTON CALIPER/BRACKET, RADIAL MASTER CYLINDER, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This setup replaces your entire front braking circuit for supermoto use. It moves the bike from a sliding OEM setup to a rigid four-piston configuration. The radial master cylinder provides precise lever feel and increased pressure at the caliper. A floating 320mm rotor manages the high thermal loads of tarmac racing without warping. You must bleed the system thoroughly after installing the braided line. This kit is model-specific to ensure the bracket aligns perfectly with your fork lugs. It is a complete bolt-on solution for riders moving from dirt to track.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron Stable — a UK shop for motocross, enduro, and trail-bike hard parts. Every fitment lives on the site, listed against KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is the data: fully enriched fitment so you find the right part for your bike quickly and get it fitted accurately. 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 and e-moto only. We operate from our storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. The business has a rich motorcycle history across multiple moto brands — the photos show where we came from — and recently pivoted into hard parts and online retail.
