BENELLI 650 Tornado S (1972-1973) Specs, Performance & Photos

In 1972, following Alejandro de Tomaso's acquisition of Benelli, the maker introduced a revised version of the Benelli 650 Tornado under the Benelli 650 Tornado S designation, featuring several modifications.

The 1972 model had an electric starter, a rebalanced crankshaft, increased compression, revised gear ratios, and Veglia instruments. Several components were rubber-mounted to minimize the vibration effects, and weights were added to the handlebar ends.

In addition, the Tornado motorcycles made for the American market differed from those made for the European market in small details such as the handlebar and seat.

Visually, the motorcycle was characterized by standard fittings, like a round headlight upfront, a chromed front fender, a dual seat, a two-into-two exhaust system with a muffler mounted on each side, side-mounted rear shocks, and 18-inch wire-spoke wheels.

In the performance department, the 1972 Benelli 650 Tornado S had its heartbeat set by a 642cc four-stroke air-cooled parallel-twin engine that delivered a power output of 52 hp with a peak force at 7,200 rpm. The power generated by the engine was controlled by a five-speed transmission linked to the rear wheel via a final chain drive.

The motorcycle packed a Marzocchi tele-hydraulic fork handling suspension on the front and a drum braking unit controlling stopping power. In contrast, the rear end was controlled by twin shocks and a drum braking unit.
