Vertex 24244C Cast Replica Piston Kit Standard Bore - 72mm 300cc

The Vertex 24244C Cast Replica Piston Kit is a precision-engineered OEM-replacement piston kit designed for 300cc two-stroke engines. Manufactured in Italy, Vertex is the OEM piston supplier to KTM and numerous European motorcycle manufacturers, making this kit a trusted choice for riders seeking a direct, factory-quality replacement.

This is a "C" grade standard bore kit with a piston diameter of 71.945mm for a 72.000mm cylinder bore, maintaining the stock OE compression ratio on 300cc displacement engines. The gravity-cast aluminum alloy construction incorporates 18% silicon content, delivering an exceptionally light yet strong piston with reduced thermal expansion for tighter running tolerances, more power, less noise, and extended service life.
