§ 02 / About this part

What it is

The PROX PISTON KIT FORGED 94.95MM B, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

Restore lost compression and engine response with this forged top-end refresh. This component sits inside the cylinder bore, converting combustion into mechanical drive. The forged construction offers increased structural integrity for high-performance four-stroke applications. Regular replacement is essential to prevent skirt fatigue or catastrophic failure in high-hour engines. This B-sizing allows you to maintain tight tolerances as your bore wears. It serves as a direct alternative to OEM part 786.30.007.000. During your rebuild, verify the ring end-gap and ensure the piston arrow points toward the exhaust port. Always use new circlips and lubricate the gudgeon pin thoroughly.

§ 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.
