Vehicle assignment

The forged piston is assigned to the KTM 250 EXC F from the years 2007, 2008, 2009, 2010, 2011, 2012 and 2013. The model and year of manufacture therefore serve as a central selection aid for this engine part.

Execution and selection

The piston diameter of 75.97 mm, the bore diameter of 76.01 mm and the marking B with an oversize of +0.01 are particularly relevant for the assignment. The forged double bridge describes the specific design of the piston. The component is specified as a 4T version and has 2 rings.
