§ 02 / About this part

What it is

The VERTEX PISTON KIT Ø 89.00 B, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

Refresh your top-end to maintain the reliability of your large-bore engine. This kit sits in the cylinder and is responsible for converting combustion into drive. Four-stroke pistons face significant stress, and worn rings will eventually lead to oil burning and lost power. This B-size kit is designed to match cylinders with slight wear, providing a precise fit. It includes the piston, rings, gudgeon pin, and circlips. Confirm your cylinder is within tolerance using a bore gauge before installation. Always check ring end gap and ensure the piston is oriented correctly to prevent engine damage.

§ 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.
