The duct and the exhaust port have been made with a new design to increase engine efficiency.

The piston has been completely redesigned with large passages on the skirt to facilitate the feeding of the transfer lines.

The head with increased finning on the entire surface allows for maximum heat dispersion. The dome is entirely machined and coupled with a copper gasket to improve performance and optimize cooling; the dowel pins with the cylinder allow for a constant squish area over the entire diameter of the cylinder.
