§ 02 / About this part

What it is

The PROX PISTON KIT ALUMINUM 65.50MM STANDARD, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This standard-size kit replaces OEM part 13101-KFB-750 to maintain factory tolerances. It is the core of your top-end, sitting inside the cylinder to facilitate the combustion cycle. Regular replacement prevents catastrophic failure and maintains peak torque. Use this for a standard bore that shows no significant wear or ovality. Lubricate the wrist pin and small-end bearing thoroughly during assembly. Check that the rings are seated correctly in their grooves to avoid snagging a port. This is a direct drop-in for your rebuild.

§ 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.
