The Vertex pistons are pistons manufactured by casting from aluminium and silicon to withstand the highest temperatures without losing their properties.
This ensures a significant increase in terms of power and durability, with the assurance of a quieter operation and no breakages.

The presence of a high silicon content also allows for better wear resistance and therefore prolongs the service life of the piston without loss of performance.
