§ 02 / About this part

What it is

The WISECO PISTON KIT YAM YZ65 18-19, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

Small-bore engines operate at high RPM, making regular top-end maintenance essential. This assembly replaces the piston, rings, pin, and clips to restore compression and prevent skirt failure. Replace these parts at the intervals specified in your race schedule to avoid cylinder damage. Measure your bore to ensure this size matches your current cylinder grade. Point the arrow on the piston crown toward the exhaust port during the rebuild. Always check the ring end gap before fitting to ensure the engine can handle the high thermal loads of competitive racing.

§ 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.
