§ 02 / About this part

What it is

The WISECO PISTON KIT PRO-LITE, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This forged unit is engineered for high-performance top-end refreshes. It replaces the stock piston to offer better durability under race conditions. You should swap this out at the recommended service interval to avoid loss of power or potential engine damage. The kit comes complete with rings, gudgeon pin, and circlips. Verify your cylinder bore size and condition before ordering to ensure the correct tolerance. During the rebuild, pay close attention to ring orientation and end gap. This part is essential for maintaining the mechanical integrity and throttle response of your bike.

§ 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.
