Features:

Cooling Head: The 'Lighter & Lower evolution 2' type cooling head has been drilled and milled out to reduce the mass of the cooling head, reducing the Center of Gravity of the engine/car.

Piston: The material of this piston has been chosen for its excellent strength to weight properties. The shape of the top of the piston features Novarossi's 'Compact Combustion Technology' which improves the efficiency of the engine. This piston is also milled from a single block which further increases the strength.

Conrod: The R7 conrod is made from a super light aluminum which has been ultrasonically tested. The shape of the R7 rod reduces turbulence inside the engine while running.

Sleeve: The sleeve has 7 transfer ports and an exhaust with booster ports. The special shape and positioning of the ports, covered by a patent, improves the internal fluid-dynamics to obtain maximum performance.

Rear Cover: The rear cover optimizes the case volume and reduces dead space. The steel plate reduces friction and extends the lifespan of the conrod.

Crankshaft: The crankshaft has a special shape to reduce turbulence inside the crankcase. The front part was extended to improve the seal and help to reduce fuel leaking.

Rear Ball Bearing: The rear ball bearing has high quality ceramic balls to minimize wear and inertia to improve acceleration and fuel consumption.

Carburetor: The carburetor is made from plastic, in "reverse" style and has a sliding throttle valve.

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.

Glowplug: The glowplug of engine is a Turbo type glowplug. Turbo glowplugs have a different shape than Standard glowplugs and therefor are not interchangeable able with engines that use Standard glowplugs!
