This piston kit is essential for maintaining your 2-stroke top-end. It sits in the cylinder bore to provide the seal required for combustion. The B-size allows for precise fitment as your cylinder wears over time. Regular piston swaps prevent skirt fatigue and maintain the sharp throttle response expected from a race bike. Clean the exhaust port and power valve assembly while the top-end is disassembled. Measure your bore accurately to select the correct size. The kit includes the piston, rings, pin, and circlips for a professional workshop installation.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron Stable — a UK shop for motocross, enduro, and trail-bike hard parts. Every fitment lives on the site, listed against KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is the data: fully enriched fitment so you find the right part for your bike quickly and get it fitted accurately. 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 and e-moto only. We operate from our storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. The business has a rich motorcycle history across multiple moto brands — the photos show where we came from — and recently pivoted into hard parts and online retail.
