§ 02 / About this part

What it is

The VERTEX PISTON KIT Ø 39.00 B, top end. 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 — 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.
