§ 02 / About this part

What it is

The PROX PISTON KIT FORGED 99.96MM B, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This B-grade forged kit is designed for cylinders that have experienced minor wear and require a slightly larger diameter to maintain correct clearances. It replaces OEM part 817.30.007.100 and is essential for maintaining power in your big-bore engine. Forged units offer the strength required for high-torque applications. Regular maintenance prevents the assembly from rocking in the bore, which can damage the Nikasil coating. This kit includes the rings, pin, and clips. Always use a fresh gasket set when installing this kit to ensure a reliable, leak-free seal.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron stable — this is a UK shop for motocross, enduro, and trail-bike hard parts. All fitments live on the site, and listed against MX models KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is in the data, fully enriched to assist with accurate fitting and finding the right part for your bike quickly and easily. 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 & e-moto only. We operate from our huge storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. We have a RICH motorcycle history with multiple moto brands the images showing where we came from and our history, the business recently pivoted into hard parts and online retail.
