§ 02 / About this part

What it is

The WISECO PISTON RING SET, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

Restore compression and seal your combustion chamber during a mid-season refresh. These rings are essential when your bore is still within tolerance but performance is dropping. Check your end gap carefully before installation to ensure optimal heat transfer and oil control. Replacing rings at the correct service interval prevents unnecessary wear on the cylinder walls. This set is designed for specific bore sizes to match your existing piston. Keep your top-end tight and responsive for the next race.

§ 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.
