§ 02 / About this part

What it is

Vertex piston top-end kit, part number 09104389.

Fresh engine internals restore lost compression and maintain reliability. These components replace the worn assembly and gudgeon pin at the heart of your bike. Regular replacement prevents skirt failure and cylinder damage during high-hour service intervals. Sizing letters A through D allow precise matching to your specific bore diameter. Check your measurements before selection to ensure the correct clearance. Always verify ring end gap and seat the circlips correctly during assembly. This provides an exact OEM cross-reference for a straightforward workshop install. It is a standard requirement for any serious race or trail rebuild.

§ 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.
