§ 02 / About this part

What it is

Athena top-end gasket kit to fit the Honda NX 500, model years 1988–1996, 1999; Honda XBR 500, model years 1985–1987; and Honda XR500R, model years 1983–1984.

Seal your rebuild with a comprehensive set of gaskets. This kit includes the head gasket, base gasket, and necessary O-rings to refresh the upper engine. It is essential whenever you pull the cylinder to inspect the piston or bore. These components are designed to withstand the high thermal loads of racing. Ensure all mating surfaces are perfectly clean and flat before installation. Using new gaskets prevents coolant leaks and pressure loss in the combustion chamber. This kit provides a reliable seal for your specific bike model.

§ 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.
