BENELLI Sport Models/Series Timeline, Specifications & Photos

The Benelli Sei was a series of motorcycles manufactured by Benelli and masterminded by automotive designer Alejandro de Tomaso from 1973 to 1989. The series was available in 750 and 900cc displacements. In addition, the 750 model was the first production machine fitted with a six-cylinder engine.

In 1983, the Italian motorcycle maker introduced the Benelli 900 Sei Sport, a naked motorcycle powered by a six-cylinder engine. Compared to the Benelli 750 Sei, the Sport version was similar but with a larger bikini fairing.

Standard fittings complemented the bike's appearance, like a larger fairing with a small windscreen, a one-piece, two-up seat, side-mounted rear shock absorbers, a six-into-two exhaust system with a chromed silencer on each side, and 12-spoke aluminum alloy wheels.

As for the power figures, the 1983 Benelli 900Sei Sport boasted 80 hp with a peak force at 8,400 rpm from a 906cc four-stroke six-cylinder air-cooled engine mounted at its core. It was fed by three 24 mm Dell'Orto carburetors and pushed the motorcycle to a top speed of 199 kph (120 mph).

Suspension-wise, the motorcycle packed a telescopic fork on the front and five-way adjustable shock absorbers on the rear, providing optimum handling capabilities.

As for the stopping power, the motorcycle's wheels were fitted with two 294 mm brake discs on the front with dual-piston calipers and a 255 mm brake disc on the rear with a single-piston caliper.

In 1982, the Italian motorcycle manufacturer launched the Benelli 654 Sport, a touring version that wore the handlebar and saddle of the Benelli 350 Sport II and the graphics of the Benelli 125 2C Sport.

This wasn't enough to boost sales due to its outdated mechanics and bad reputation. In addition, it was the most expensive motorcycle in the segment, even than the Honda CB650 and BMW R 65.

In the performance department, the 1982 Benelli 654 Sport had its soul brought to life by a 604cc four-stroke four-cylinder air-cooled engine that delivered a power output of 60 hp at 8,700 rpm and 50 Nm (37 lb-ft) torque at 7,000 rpm.

The energy crafted by the engine was transferred to the rear end through a five-speed manual gearbox controlled by a wet multi-disc clutch and a final chain drive.

The motorcycle was built around a tubular steel frame with a tele-hydraulic fork on the front and dual side-mounted rear shocks that offered optimum suspension and handling capabilities.

The braking power was achieved by two 265 mm brake rotors on the front and a 260 mm brake rotor on the rear, providing optimum braking performance.

In the visual department, the bike was characterized by standard features, such as 12-spoke aluminum alloy wheels, a four-into-two exhaust system with a silencer on each side, a one-piece dual seat, and a round headlight integrated into a handlebar-mounted fairing with a small windscreen.

The Benelli 354 Sport II was a middle-class naked motorcycle made by Benelli for only six years, from 1980 until 1985 when it was dropped from production. Over its production years, the bike remained unchanged without any modifications.

In 1981, the Italian motorcycle maker released the Benelli 354 Sport II, a naked motorcycle in its second production year, featuring the same characteristics as the previous one without any significant modifications.

The bike was made around a tubular steel frame with a hydraulic telescopic fork handling the front-end suspension and a dual-sided swingarm with side-mounted shocks handling the rear-end suspension.

In the braking department, the motorcycle's 18-inch wheels were fitted with two brake discs on the front and a single brake disc on the rear clamped to hydraulic calipers, offering optimum stopping power.

As for the power figures, the 1981 Benelli 354 Sport II took its muscles from a 345cc four-stroke four-cylinder air-cooled engine, boasting 38 hp with a peak force at 10,200 rpm. The engine was fitted with a five-speed transmission, pushing the motorcycle to a top speed of 160 kph (99 mph).

Aesthetically, the motorcycle was fitted with features like 12-spoke aluminum alloy wheels, a four-into-two exhaust system with a silencer mounted on each side, side-mounted rear shocks, a one-piece dual seat, and a round headlight integrated into a small cowl with a small windscreen.

In 1980, the Italian motorcycle manufacturer introduced the Benelli 504 Sport, a middle-class naked two-wheeler designed to satisfy the needs of riders with different experience levels and ages.

The bike's riding characteristics were set by a double-cradle steel frame with a hydraulic telescopic fork mounted on the front and two side-mounted shocks on the rear with five-way spring preload adjustability.

As for the braking performance, the motorcycle's wheels were fitted with two 260 mm brake rotors on the front and a 260 mm brake disc on the rear. All discs were clamped by hydraulic calipers, offering optimum stopping performance.

In the performance department, the 1980 Benelli 504 Sport had its soul brought to life by a 498cc four-stroke air-cooled four-cylinder engine mounted underneath its fuel tank, delivering 52 hp with a maximum peak at 9,400 rpm and 43 Nm (32 lb-ft) torque at 9,300 rpm.

The power was sent to the rear through a five-speed gearbox and a final chain drive, launching the machine to a maximum speed of 172 kph (107 mph).

As for the visual characteristics, it was fitted with standard fittings, like a large, round headlight integrated into a cowl with a small windscreen, a one-piece dual seat with passenger grab handles, a four-into-two exhaust system with a silencer mounted on each side, a center stand, and 12-spoke aluminum alloy wheels.
