§ 02 / About this part

What it is

The ATHENA TOP END GASKET KIT, gaskets & seals. Stocked by Iron Offroad, the UK MX hard parts specialist.

This set includes the head gasket, base gasket, and necessary O-rings for a top-end refresh. It is essential when replacing your piston or rings to maintain compression. These parts sit between the cylinder, head, and crankcase. Heat cycles and high pressure eventually degrade the original seals. Always check your squish clearance when installing the base gasket. This kit matches OEM dimensions for reliable sealing under race conditions. Clean the mating surfaces thoroughly to prevent coolant or oil migration.

§ 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.
