§ 02 / About this part

What it is

The VERTEX PISTON KIT Ø 78.00 B, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This B-sized kit corresponds to OEM part 79030207000 and is designed for cylinders with moderate runtime. It restores the factory-specified clearance for optimal compression and oil control. It sits in the top-end of your 250cc four-stroke engine. Replace this kit at the service intervals suggested by the manufacturer to prevent catastrophic engine failure. The kit includes the piston, rings, gudgeon pin, and circlips. Ensure the ring gaps are staggered according to the workshop manual. Clean the cylinder head and valves thoroughly while the top-end is disassembled.

§ 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.
