§ 02 / About this part

What it is

The VERTEX PISTON KIT PRO REPLICA Ø 90.00 A, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This component is a direct replacement for OEM part 3402-846. It sits in the top-end, engineered to provide factory-level reliability and performance. The 90.00mm (A) sizing is intended for cylinders within original factory tolerances. Regular maintenance of the piston and rings is essential to prevent blow-by and maintain engine torque. Before fitting, verify the ring end gap and ensure the gudgeon pin is properly lubricated. Orientation is vital for correct port timing and cooling. This kit includes the piston, rings, pin, and circlips for a professional top-end service.

§ 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.
