The Benelli Sei was a family of motorcycles manufactured by Benelli and masterminded by Alejandro de Tomaso from 1973 until 1989. The bikes were available in 750 and 900cc displacements, while the 750cc model was the first production motorcycle that featured a six-cylinder engine.
In 1973, the Italian motorcycle manufacturer launched the Benelli 750 Sei, a powerful naked machine driven by the first six-cylinder engine mounted on a production motorcycle. The engine was based on the one installed in the Honda 500 but had two additional cylinders.
The bike's visual department was characterized by features such as a one-piece dual seat with a pillion grab rail, a round headlight upfront, a chromed front fender, a three-into-three exhaust system with three silencers mounted on each side, and wire-spoke wheels.
The 1973 Benelli 750 Sei was powered by a 748cc four-stroke six-cylinder air-cooled engine that delivered a power output of 76 hp at 9,000 rpm. A five-speed transmission with a wet clutch sent the power to the rear wheel, pushing the motorcycle to 204 kph (127 mph).
As for the stopping power, the motorcycle's wheels were fitted with two 300 mm brake discs clamped to dual-piston calipers on the front and a 200 mm drum braking unit on the rear, offering excellent braking performance.
