The Pro-X motorcycle piston for the Yamaha YZ 125 is gravity cast from an aluminum alloy containing approximately 18% silicon. The silicon reduces the piston’s thermal expansion. Its designs are generally similar to standard OEM configurations, with some modifications made where the potential for improved performance is identified.
The piston is intended for two-stroke engines and is suitable for cast-iron or Nikasil cylinder liners.
