§ 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, brakes. 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.
