§ 02 / About this part

What it is

The WOSSNER PSTN KT HON CRF250R STD B, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This forged piston kit is designed for CRF250R cylinders with higher hours. The Standard B diameter compensates for bore wear to restore the correct piston-to-wall clearance. It is a critical service item for maintaining compression and engine response. The kit features a forged piston, rings, gudgeon pin, and circlips. Use a bore gauge to confirm your cylinder requires the B-size fitment. Pay close attention to ring orientation and gap during the installation. Proper assembly ensures the longevity of the top-end under race conditions. Clean the cylinder thoroughly to ensure the new rings seat correctly during break-in.

§ 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.
