These 2023 engines are totally new and are different from the previous version in the following details:

– New high dissipation and low density aluminum cooling head, to combine functionality and lightweight;
– New crankshaft, with revised timing and balancing;
– New piston and liner, 5 PORTS with high compression piston made from rod;
– New reinforced conrod

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.

Hasi engines are made to order – please note this is usually a 7-10 day turnaround.
