§ 02 / About this part

What it is

The PROX MASTER CYL REBUILD KT FR, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

ProX front master cylinder rebuild kit for KTM and Husaberg, spanning the two-stroke EXC and SX range from 125 through 525 plus the 400 LC4 and FE/FS four-strokes. Grit creeps past the dust boot and scores the piston seals, and your front lever loses bite or weeps fluid at the lever body. The kit carries the piston, spring, seals and circlips for a full internal overhaul. Check the bore for pitting before you fit; a scored bore needs the whole cylinder. Bleed with the DOT fluid your bike specifies. Restores lever feel without the cost of a new assembly.

§ 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.
