§ 02 / About this part

What it is

The VERTEX PISTON KIT Ø 45.00 C, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This piston is a direct cross-reference for OEM part 8000H7155. The (C) sizing indicates a slightly larger diameter, ideal for cylinders that have worn beyond (A) or (B) tolerances. It sits in the top-end to restore compression and eliminate piston slap. Periodic replacement is necessary to protect your cylinder plating and maintain performance. When installing, verify the ring end gap and ensure the arrow on the crown points toward the exhaust port. This kit includes the piston, rings, gudgeon pin, and circlips for a precise top-end refresh.

§ 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.
