§ 02 / About this part

What it is

The VERTEX PISTON KIT Ø 39.00 B, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This kit refreshes the upper engine of your small-bore bike to maintain compression and reliability. It sits inside the cylinder and requires replacement as the rings and skirts wear down. Use the B size as the cylinder wears to maintain correct clearances. Regular changes are critical on small-capacity engines to prevent catastrophic failure. The kit includes the piston, rings, gudgeon pin, and circlips. Check your ring end gap and ensure the circlips are fully seated. Orient the crown correctly according to the markings. Maintaining your top-end ensures consistent power delivery.

§ 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.
