§ 02 / About this part

What it is

The MOTO-MASTER BRAKE CALIPER KIT 4 PISTON CALIPER + ADAPTER SM RACING BLACK, brakes. Stocked by Iron Offroad, the UK MX hard parts specialist.

Move beyond the limitations of your OEM slider caliper. This 4-piston unit provides massive clamping force and a firm, consistent lever feel. It is designed specifically for supermoto racing where braking demands are extreme. The included adapter bracket aligns the caliper perfectly with your fork lugs. This setup reduces brake fade and offers superior modulation compared to standard off-road components. It is a significant upgrade for any bike converted for track use. Ensure your master cylinder displacement is compatible with the increased piston volume for optimal performance.

§ 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.
