§ 02 / About this part

What it is

The VERTEX PISTON KIT 24387B, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This piston kit is a key element for your engine rebuild. The B-sizing is designed to compensate for slight cylinder bore wear. Regular replacement is vital to prevent skirt fatigue and ring failure during high-rev operation. This kit includes the piston, rings, gudgeon pin, and circlips. Always check your ring end gap before installation. Ensure the arrow on the piston crown points toward the exhaust port. Proper lubrication of the small-end bearing is essential during assembly. Follow your service manual for torque specs on the cylinder head.

§ 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.
