Perform your top-end service with confidence. This kit includes the head, base, and exhaust gaskets required for a piston or ring change. These components sit at the heart of the combustion chamber and cooling circuit. Heat cycles eventually degrade the original seals, leading to compression loss or coolant leaks. Each part follows OEM dimensions for exact port alignment. Clean the cylinder and head surfaces thoroughly to prevent blow-by. It is standard practice to replace these every time the cylinder is pulled for inspection.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron Stable — a UK shop for motocross, enduro, and trail-bike hard parts. Every fitment lives on the site, listed against KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is the data: fully enriched fitment so you find the right part for your bike quickly and get it fitted accurately. 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 and e-moto only. We operate from our storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. The business has a rich motorcycle history across multiple moto brands — the photos show where we came from — and recently pivoted into hard parts and online retail.
