Dettagli

Coolinghead: This a 'Lighter&Lower evolution 2' type of cooling head. It is drilled and milled out to reduce the mass of the coolinghead which sits high up in the car and thereby lowering the Center of Gravity of the engine/car.

Sleeve: The sleeve has 4 transfer ports , the best compromise to make a linear power supply with minimal fuel consumption combination possible.

Crankshaft: As this engine comes as "Factory Tuned" we have modified the crankshaft to futher improve the power output and driveability.

Gasket: The inner shape of the gasket has a new shape, and with that more material.Together with a change in material these gaskets are more resistant to high temperatures.

Conrod: The R7 conrod is made from a superlight alluminium which has been checked ultrasonic. The specific form of the R7 creates little turbulence inside the engine while running.

Backplate: The rear cover presents a round shape to optimize the filling and reducing the dead spaces. the steel plate is to reduce friction and to expand the lifespan of the conrod.

Carburettor: The carburettor of this engine is made from plastic and in "reverse" style and has a sliding throttle valve. The new three tuning needles gives a better idle and improves the ability of the engine to return to low rpm after throttling.

Rear ball bearing: The new ball bearing reduces the inertia of the rotating masses and increases the engine's scavenging. You can see both the ball bearing and the manufacturing process result in the picture. These novelties give an increased throttle response and a higer top speed.
