§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 98.00MM +1.00MM, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This oversize piston kit is for engines requiring a 1.00mm overbore. It cross-references with OEM part 13101-MN1-680. Use this when your cylinder bore is damaged or worn beyond standard limits. It sits at the heart of the top-end and restores the seal between the combustion chamber and the crankcase. The kit includes rings, pin, and clips. Your cylinder must be bored and honed to 98.00mm to accept this fitment. Verify the piston-to-wall clearance during the machining process. Ensure the arrow on the crown points toward the exhaust port during your rebuild.

§ 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.
