Features:

• Sleeve: The 7-Port Sleeve has been Modified to improve low end power. The shape and positioning of the ports, improves the internal fluid-dynamics to obtain maximum performance and has been protected by a patent.
• Piston: The material for this piston was chosen for its strength and weight properties. The shape of the piston features Novarossi's "Compact Combustion Technology" which helps to improve efficiency.
• Lighter & Lower Cooling Head: The cooling head has been re-designed so that it is mounted lower on the case for a lower center of gravity, with additional machine work to reduce weight and improve cooling efficiency.
• R7 Conrod: This rod is produced from ultrasonic tested, super light aluminum, and is designed to help eliminate turbulence during operation.
• Crankshaft: The crankshaft has a special shape to reduce turbulence inside the crankcase. The front part has been extended to improve the seal at the front bearing to help prevent fuel leaking.
• Combustion Chamber: The combustion chamber is supported by an O-Ring which is placed between the combustion chamber and the crankcase to reduce the vibrations of the combustion chamber.
