§ 02 / About this part

What it is

The WOSSNER PIST KIT KX250 21+ 77.97, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

Restore the performance of your KX250 with this precision top-end kit. The piston operates under extreme pressure within the cylinder, where ring wear eventually leads to compression loss and starting issues. Replacing the piston at set service intervals prevents skirt failure and bore damage. This kit includes the piston, rings, gudgeon pin, and circlips. This 77.97mm sizing is for cylinders with minor wear. During installation, ensure the ring gaps are staggered according to the workshop manual. Lubricate the small-end bearing thoroughly before closing the top-end.

§ 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.
