These 2023 engines are totally new and are different from the previous version in the following details:
– New high dissipation and low density aluminium cooling head, to combine functionality and lightweight;
– New crankshaft, with revised timing and balancing;
– New piston and liner, 9 PORTS with high compression piston made from rod;
– New reinforced conrod
These also included the OPTIONAL ceramic rear bearing installed.
Each engine will have its own dedicated sleeve, which will be perfectly honed inside the crankcase, avoiding dangerous vibrations; the design of the ports has been revised to combine performance and reliability.
Like every Hasi engine, they are numbered one by one and accompanied by a certificate of guarantee and authenticity and the useful engine book.
