PROX cast piston for KTM 250 XC W 2021-2027

The PROX cast piston is intended for the KTM 250 XC W in the entire 2021-2027 model year range. The design combines a cast piston type with standard piston compression and is therefore suitable as a precisely defined component for the engine of this vehicle classification.

Function and execution

The piston is made of aluminum. PROX manufactures pistons from a special alloy that helps minimize friction and thus ensure high reliability. Careful development work supports the precise design of the piston for the intended area of ​​application.

The piston skirt has a MoS2 coating. This feature, together with the curved piston shape, is part of the specified specification and makes selection easier based on the technical design.
