§ 02 / About this part

What it is

The ATHENA CYLINDER KIT 144cc 58mm BIG BORE, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This assembly increases displacement for more torque and mid-range pull. It replaces your original top-end components with a larger bore diameter. You will notice the difference on steep climbs and deep loam. Because the bore size changes, you must adjust your jetting or fuel mapping to suit the increased air volume. The assembly includes the gaskets and piston required for the conversion. It is a bolt-on performance upgrade for your bike. Check your squish clearance during assembly.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron stable — this is a UK shop for motocross, enduro, and trail-bike hard parts. All fitments live on the site, and listed against MX models KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is in the data, fully enriched to assist with accurate fitting and finding the right part for your bike quickly and easily. 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 & e-moto only. We operate from our huge storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. We have a RICH motorcycle history with multiple moto brands the images showing where we came from and our history, the business recently pivoted into hard parts and online retail.
