This Athena replacement top end piston kit is designed for the specific KTM applications listed below. Made of high-performance aluminum alloy with high silicon content that guarantee the same reliability of the OE piston, while at the same time providing greater resistance and excellent performance.

Key Features

• Made of high-performance aluminum alloy with high silicon content that guarantee the same reliability of the OE piston, while at the same time providing greater resistance and excellent performance.
• The smooth profile ensures a regular flow and the perfect flame propagation.
• The piston for 2-stroke Off-Road are produced by numerical control (CNC) machines.
• Made of special high performance aluminum alloy with high silicon content that guarantee the same reliability of the OE piston.
• Piston rings guarantee high seal to the cylinder walls with less friction and therefore a higher performance.
• The gasket kit is produced following the strict parameters set by the manufacturers.
• The gasket is made from raw materials and performs surface treatments to compensate for surface irregularities and follows material stress relieving process to improve sealing in the most critical areas.
