§ 02 / About this part

What it is

The VERTEX PISTON KIT HC Ø 79.00 B, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This high-compression component is designed to boost torque and mid-range pull. It sits in the top-end and features a modified crown profile to reduce combustion chamber volume. This B-size kit is intended for cylinders that have seen moderate use. High-compression setups require high-octane fuel to prevent detonation. Monitor your coolant levels and radiator condition as this part increases thermal load. Check your squish clearance during installation to ensure safe operation. It is a direct replacement for the standard unit during a performance rebuild 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.
