§ 02 / About this part

What it is

The ATHENA CYL KIT STD BORE SU, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This kit refreshes your top-end with a standard bore cylinder and matched piston assembly. It replaces worn or scored factory barrels that have lost compression or suffered heat damage. The kit includes the necessary gaskets and hardware for a clean install. Ensure you check your crank play and small-end bearing before fitting. It provides a direct alternative to OEM parts without the need for re-plating. Proper heat cycles are essential during the first hour of use to bed in the rings and ensure longevity.

§ 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.
