§ 02 / About this part

What it is

Vertex piston kit Ø78.00 C to fit Gas Gas MC250F (2021–2023); Husqvarna FC250 (2016–2022); KTM SX-F250 (2016–2019); KTM XC-F250 (2016).

This C-sized piston kit is intended for 250cc four-stroke cylinders that have moved beyond the A and B tolerances. It provides a precise fit for worn bores, ensuring compression remains high. It sits in the top-end and is a vital part of a comprehensive engine refresh. Regular maintenance prevents the piston from rocking, which protects the cylinder plating. The kit includes the piston, rings, pin, and circlips. Measure your bore with a dial bore gauge to confirm the C-size is appropriate. Always use fresh engine oil to lubricate the rings and cylinder wall during assembly.

§ 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.
