§ 02 / About this part

What it is

The WOSSNER PSTN KT HON TRX420 +.50, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This +.50mm kit is designed for TRX420 engines needing a cylinder refresh. The oversize diameter allows for a rebore to remove wear and restore a perfect sealing surface. Reliable operation in utility applications depends on a healthy top-end with high compression. This kit contains the piston, rings, gudgeon pin, and circlips. Precision machining is required to match your cylinder to this piston size. Check the valves and seats for wear while the head is removed. Always use new gaskets and follow the correct torque sequence during reassembly to ensure engine integrity.

§ 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.
