This is Novarossi New VIR-TUS .21OFF/S Buggy.

FEATURES

Patented:
The shifted carburetor grants a better mixture flow inside through the crankase's intake. This gives the engine an improved fuel efficiency and a better power curve. .

Crankcase

The new crankshaft gives the engine a better balancing. This will reduce the vibration produced by the rotating and the alternating masses.

Cooling head

This a 'Lighter&Lower evolution 3' 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. The use of 6 screws instead of 4 ensures a better sealing between sleeve, botton head and the crankcase.

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 above. These novelties give an increased throttle response and a higer top speed.

9 Ports ABC Piston 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, improve the internal fluid-dynamics to obtain the maximum possible performance.

Crankshaft TURBO

The new crankshaft gives the engine a better balancing. This will reduce the vibration produced by the rotating and the alternating masses.

Rear Cover

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.

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.
