§ 02 / About this part

What it is

The WISECO PISTON KT YZF250 19-, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

Refresh your YZF250 top-end to maintain its high-rpm performance. Four-stroke pistons endure massive thermal stress, leading to ring tension loss and oil consumption over time. This kit replaces the piston, rings, and gudgeon pin to restore the engine to factory specifications. It is a critical service item for race-tuned bikes to prevent conrod and valve damage. Check your valve clearances while the head is removed for this install. Ensure the piston rings are oriented correctly to prevent oil blow-by. This kit offers a technical alternative to the standard OEM part.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron stable — this is a UK shop for motocross, enduro, and trail-bike hard parts. All fitments live on the site, and listed against MX models KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is in the data, fully enriched to assist with accurate fitting and finding the right part for your bike quickly and easily. 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 & e-moto only. We operate from our huge storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. We have a RICH motorcycle history with multiple moto brands the images showing where we came from and our history, the business recently pivoted into hard parts and online retail.
