The MONZA EVO 3,5cc features a newly designed crankcase that improves internal gas flow and therefore higher performance at every range of RPM. The 14mm crankshaft with silicone insert is DLC coated in order to prevent wear of the pin and oxidation. The shaft works on a high quality rear ceramic Swiss-Made bearing. The 7 port “cylinder and piston” is made with special alloys to optimize life and reliability of the unit. Paired with the long stroke scheme the MONZA EVO provides great bottom power to suite the demanding high grip on-road tracks. The super aligned “knife edged” aerodynamic connecting rod is also made with a special aluminum alloy.  The  aluminum die-casted carburetor sports the latest double bottom-end adjustment for a fine-tuning.
