§ 02 / About this part

What it is

The VERTEX PISTON KIT PRO REPLICA Ø 76.80 A, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This kit serves as a direct replacement for Honda OEM part 13101-KRN-B10. It is an A-sized component for fresh or low-hour CRF250R cylinders. The piston sits at the core of your top-end, converting combustion into drive. Four-stroke pistons face extreme thermal stress and require replacement to avoid oil consumption and power loss. This kit includes the rings, pin, and circlips. Use a torque wrench on the cylinder head bolts to ensure even clamping pressure. Always replace the head gasket when fitting a new piston kit to ensure a reliable seal on your bike.

§ 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.
