§ 02 / About this part

What it is

Athena cylinder head gasket to fit Honda NX 650 (1988–2000); Honda XR650L (1993–2009, 2012–2019); Honda XR650R (2003, 2005, 2007).

This seal is the critical interface between the cylinder and the head. It maintains compression and prevents coolant from entering the bore. Replace this every time you pull the top end for a piston change or valve service. Heat cycles eventually degrade the material, leading to pressure loss. This part matches OEM cross-references 12251MN9003, 12251MN9013, 12251MN9741, and 12251MN9742. Always use a torque wrench to tighten head bolts to factory specifications. Ensure both surfaces are perfectly flat and clean. It is essential for maintaining engine performance on your bike.

§ 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.
