§ 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 forged piston kit is built for the high-stress environment of a modern 4-stroke top-end. The forging process increases structural density to handle high RPM and compression ratios. It sits at the heart of your engine, converting combustion into mechanical force. Replace your piston at recommended hour intervals to avoid skirt failure or ring groove wear. This kit includes the piston, rings, pin, and clips. It cross-references with OEM part 5VK-11631-00. Measure your cylinder bore accurately to ensure the correct clearance for this B-size piston.

§ 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.
