The 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 AAC 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.
These engines are made to order – approx lead time is 14 days.
