§ 02 / About this part

What it is

The VERTEX PISTON KIT R SX125 01-/EXC125, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This top-end kit is for the 125cc two-stroke engine. It sits in the bore and manages the combustion process. Regular replacement is necessary to maintain the high-RPM performance these bikes are known for. This kit includes the piston, rings, gudgeon pin, and circlips. Measure your cylinder bore to ensure this size provides the correct clearance. Inspect the cylinder for any glazing and deglaze if necessary. Use a new base gasket to set the correct deck height. Lubricate the rings before sliding the cylinder on.

§ 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.
