PROX cast pistons for KTM 250 EXC from 2006 to 2026

The PROX cast piston is tailored to the KTM 250 EXC in the entire 2006-2026 model year range. Its special aluminum alloy is designed for low friction and thus supports reliability-oriented use in the engine. PROX's careful development work aims to find a suitable piston design for the respective area of ​​application.

Execution and function

As a cast piston, the component has standard piston compression. The curved piston shape is also part of the design, as is the MoS2 coating on the skirt. These features describe the structural design of the piston and facilitate targeted selection for the specified vehicle application.
