§ 02 / About this part

What it is

The VERTEX PISTON KIT REPLICA BB Ø 58.00 +4.00, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This big-bore kit is designed for specific cylinder conversions where the bore has been increased by 4mm. It sits in the engine and is used to increase displacement and torque. Because this is an oversize part, it will not fit a standard-sized cylinder without professional machining and replating. The kit includes the rings, pin, and clips. Ensure your cylinder head and gaskets are compatible with the increased 58.00mm bore size. This is a performance-oriented part typically used in race or modified trail applications. Verify all clearances before final engine assembly.

§ 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.
