§ 02 / About this part

What it is

The WOSSNER PISTON KIT STD TT250R 99-06 72.95 A, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This forged piston assembly sits at the heart of your top-end rebuild. It replaces the factory unit to restore lost compression and engine response. Over time, heat cycles and friction wear down the skirt and ring lands, leading to blow-by. For these trail-focused engines, oversizes allow for a fresh bore when the cylinder walls are scored or out of round. Each kit includes the piston, rings, gudgeon pin, and circlips. Always check your ring end gap before final assembly. Lubricate the pin and small-end bearing thoroughly during installation to prevent dry-start scoring.

§ 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.
