The ProX Piston Kit KTM 250 SX-F 2006-2012 / 250 EXC-F 2007-2013 (75.97mm) is the perfect high-performance piston kit for anyone looking to rebuild or upgrade their older KTM 250 4-stroke engine to top condition. This complete ProX Racing Parts kit will bring your engine back to life with reliable performance and excellent durability.

Specially developed for the KTM 250 SX-F model years 2006 through 2012 and the 250 EXC-F models from 2007 through 2013. The bore measures 75.97 mm (standard size), ideal for a direct replacement of the original piston without extra boring.

The ProX piston is CNC-machined from high-quality aluminum to strict racing specifications. Thanks to its special coating, the piston breaks in faster, reduces wear, and ensures optimal lubrication, even during intense motocross and enduro use. The compression ratio remains identical to the original, so your engine will continue to perform smoothly and reliably.
