§ 02 / About this part

What it is

The ATHENA CYLINDER KIT 450cc 95mm STANDARD BORE, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This kit updates your top-end with a complete cylinder assembly. It replaces the entire upper section of your engine to restore compression and power. Use this for a full refresh when your current bore is out of tolerance or damaged. The kit includes a precision-cast cylinder with a nickel-plated bore for reduced friction. It is designed for a precise fit without the need for engine modifications. Always check your squish clearance during assembly to ensure optimal performance. This setup provides a reliable alternative to sourcing individual OEM components for your rebuild.

§ 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.
