§ 02 / About this part

What it is

The PROX PISTON KIT FORGED 82.96MM A, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This forged A-size kit is the standard replacement for your engine rebuild. It cross-references with OEM part 8000H0507 and is designed for cylinders still within factory new dimensions. Forged components handle high RPM and thermal stress better than cast versions, making them ideal for competitive use. Timely replacement prevents rocking and preserves the cylinder walls. The kit includes the rings, gudgeon pin, and clips. Verify your cylinder bore is within the A-spec range before installation. Follow the manufacturer's torque settings for the cylinder head to ensure a proper 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.
