§ 02 / About this part

What it is

The WISECO PISTON KIT RACER'S CHOICE | GP SERIES, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This forged part is built for high-performance racing applications. It sits in the top-end, featuring a specialized design to handle extreme temperatures and high RPM. Replacing this piston at strict service intervals is critical to prevent fatigue and maintain maximum power output. Always measure your cylinder bore to ensure the clearance matches the specifications for this race-spec component. During installation, check the ring gap and ensure the circlips are oriented correctly. This kit includes the piston, rings, gudgeon pin, and clips for a comprehensive workshop 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.
