§ 02 / About this part

What it is

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

ProX rear master cylinder rebuild kit covering KTM and Husaberg EXC, EXC-F, FE, FX and SMR models from 125 up to 570. The rear circuit sits low by the swingarm, so it cops more heat and grit than the front and the seals go first. Inside you get the piston, return spring and primary seals to cure a leaking or sticking pedal. Flush the bore with brake cleaner and inspect for pitting before assembly. Copper crush washers are included, so renew them. Done properly, pedal pressure holds steady through a long moto.

§ 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.
