PROX forged pistons for KTM 250 SX F 2006-2012

The PROX forged piston is designed for the KTM 250 SX F from the entire 2006-2012 model year range. Its technical design combines aluminum with a forged piston type and standard piston compression. This allows the relevant data to be specifically compared with the existing engine and the desired oversize.

Technical execution

• Piston Type: Forged
• Piston compression: standard
• Diameter Ø: 75.98 mm
• Letter oversize: C
• Oversize: +0.02
• Rings Quantity: Set

Piston shape

The specification describes a flat crown with a raised top and 4 valve pockets. This shape is part of the defined design of the forged piston and supports clear selection based on the existing engine components.

Vehicle assignment

The piston is assigned to the KTM 250 SX F for the years 2006, 2007, 2008, 2009, 2010, 2011 and 2012. Before selection, the diameter, oversize and the specified standard compression should be compared with the technical requirements of the respective engine.

Selection note

The diameter of 75.98 mm, the oversize letter C and the oversize information +0.02 are particularly relevant for the assignment. The “4T” version denotes the specified stroke specification.
