§ 02 / About this part

What it is

The WOSSNER RING SET RST7250, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

These components seal the combustion chamber and maintain compression in your top-end. Over time, heat and friction reduce tension and increase blow-by. Replacing them restores power and prevents cylinder wall glazing. Ensure your bore size matches the specification exactly. Check the end gap before final assembly to meet OEM or manufacturer tolerances. These are critical for any mid-season refresh or full rebuild. Proper seating requires a clean bore and correct lubrication. This kit provides the necessary parts to refresh your piston seal.

§ 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.
