§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 94.96MM B, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

Step up to this B-size kit when your cylinder shows the first signs of wear. The slightly larger diameter compensates for bore growth, reducing piston slap and extending the life of your barrel. It replaces OEM part 5TG-11631-00. Regular top-end service is essential for maintaining compression and preventing oil migration. This kit comes complete with the rings, wrist pin, and circlips. Always check the ring end-gap in the bore before fitting them to the lands. Proper lubrication of the wrist pin during assembly ensures a smooth first start and reliable break-in.

§ 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.
