§ 02 / About this part

What it is

Athena top-end gasket kit to fit Kawasaki KX 80 17/14 (1998–2000); Kawasaki KX 80 19/16 (1998–2000); Kawasaki KX 85 17/14 (2001–2006); Kawasaki KX 85 I 17/14 (2007–2013); Kawasaki KX 85 II 19/16 (2007–2013).

This kit contains the essential seals for a top-end refresh or piston change. It includes the cylinder head gasket, base gasket, and exhaust seals. For four-stroke applications, it often includes valve stem seals to prevent oil consumption. For two-strokes, it covers the power valve assembly. These components handle the highest heat and pressure in the engine. Fresh gaskets ensure a proper seal against combustion gases and coolant. Clean the head and cylinder surfaces thoroughly before fitting. Always check your squish clearance after assembly to maintain engine timing and performance.

§ 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.
