§ 02 / About this part

What it is

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

When the clutch lever on a Beta goes soft, the master cylinder seals have usually given up. This ProX kit rebuilds the bore with a new piston, return spring and seal set so the circuit holds pressure. It covers the RR two-strokes from 125 through 300 and the RR four-strokes up to the 498, plus the Xtrainer 250 and 300. Match the kit to your model and the piston seats correctly in the original bore. Clean the housing out before assembly and wet the seals with fresh fluid so they slide in without nicking the lip.

§ 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.
