§ 02 / About this part

What it is

Vertex piston kit Ø76.00 B to fit KTM EXC-F250 (2007–2012); KTM SX-F250 (2006–2012); KTM XC-F250 (2007–2012); KTM XCF-W250 (2007–2012).

This B-size piston kit is a direct replacement for OEM part 77130007100. It sits in the top-end and includes the piston, rings, pin, and circlips. The B-sizing is slightly larger than standard to account for initial cylinder wear. Regular replacement is a core part of your bike's maintenance schedule to avoid skirt failure. Measure your bore to ensure the 76.00mm B-fitment provides the correct clearance. Verify the ring end gaps before fitting. Ensure the piston crown arrow points toward the exhaust. Use a new small-end bearing during the rebuild.

§ 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.
