§ 02 / About this part

What it is

The ATHENA CYLINDER KIT 125cc 54mm STANDARD BORE, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This kit replaces the entire top-end assembly on your bike. It includes the cylinder, piston, rings, and gaskets for a complete refresh. Use this when your bore is scored or beyond the service limit. The Nikasil lining provides hard-wearing durability for race conditions. It maintains OEM displacement while offering improved cooling efficiency. Check your squish clearance during assembly to ensure optimal combustion. This is a direct bolt-on solution for restoring factory compression and power. Clean all mating surfaces thoroughly before fitting the new gaskets.

§ 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.
