§ 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.
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.
