Motorcycle specifications MoriniSeiemmezzo 650 STR 2025 Six and a half sexy

Naked

founded in 1937 in Bologna, Italy, the Moto Morini brand has been owned since 2019 by the Chinese Zhongneng Group, better known in Europe as Znen Motor. At the last Milan Motor Show, in November 2021, Moto Morini unveiled a long-awaited motorcycle: the new Seiemmezzo. An Italian name meaning six and a half, a nod to the famous Moto Morini 3 1/2, released in 1971 and one of the brand's most famous models.

this roadster, with its elegant but not excessive neo-retro look, is available in two versions: STR for the on-road model (Strada) and SCR for the more off-road version (Scrambler).

all Seiemmezzo models are powered by a 649 cm3 liquid-cooled in-line twin-cylinder engine. This classic mechanical architecture develops 60 hp at 8,250 rpm and 54 Nm of torque at 7,000 rpm. With overhead camshaft and four valves per cylinder, as well as Bosch electronic fuel injection, the 6 ½ Morini is claimed to have a top speed of 175 km/h. Naturally, this new Sino-Italian meets the new Euro 5 anti-pollution standards.

with a dry weight of 200 kg and a seat height of 810 mm, it should be easy to handle. Even with its 15-liter fuel tank. The chassis consists of a tubular steel frame anchored by an aluminum swingarm. Well-equipped, the front features a 43 mm Kayaba inverted fork with 120 mm travel. At the rear, the same equipment manufacturer supplies the monoshock with the same travel as the front. Moto Morini also announces that these suspensions are adjustable

in terms of braking, the Seiemmezzo calls on Italian manufacturer Brembo to supply a pair of 298 mm-diameter discs, pinched by classic two-piston floating calipers. As for ABS, the Bosch 9.1 Mb system has been entrusted with the task. The Seiemmezzo STR is fitted with spoked wheels, while the SCR is equipped with a pair of spoke rims. Tire dimensions remain reasonable, with 120/70 x 18 at the front and 160/60x17 at the rear. From the outset, this 6 ½ " model comes with Pirelli MT60RS tires

refined , this Morini features an LED headlamp and a 5-inch TFT display. The Seiemmezzo's refinements include backlit controls and Bluetooth connectivity.

with its sleek, sexy looks, this beautiful little 6 ½ should find takers, especially as its price is closer to that of a 500 than a 650.
