§ 02 / About this part

What it is

The ATHENA TOP END GASKET KIT, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

Essential for your next piston change or top-end inspection. This kit includes the head gasket, base gasket, and necessary O-rings for the cooling system. It seals the combustion chamber and prevents coolant migration into the bore. Replace these every time you remove the cylinder to maintain compression. Check your squish clearance when fitting the base gasket to ensure optimal performance. These parts meet exact factory dimensions for a reliable seal under race conditions. It is a standard requirement for your scheduled service intervals.

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.
