§ 02 / About this part

What it is

The VERTEX PISTON KIT TOP END Ø 54.00 E, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

Restore compression and peak power with this rebuild kit. The piston sits at the heart of your engine, converting combustion into drive. Regular replacement is vital to prevent skirt fatigue and cylinder bore damage. This kit includes the piston, rings, gudgeon pin, and circlips. Sizing letters A through E allow you to match the piston to your specific cylinder wear. Always measure your bore before selecting a size. During install, check your ring end gap and ensure the crown arrow faces the exhaust port. This is a precision component designed to match OEM specifications for a reliable engine refresh.

§ 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.
