The Moto Morini Seiemmezzo STR is a 649 cc liquid-cooled roadster with a 6-speed gearbox. Bikez.com (2023 model year) lists 59 HP @ 8250 rpm maximum power, 56 Nm @ 7000 rpm maximum torque, a double-disc front / single-disc rear brake, a 120/70-ZR18 front and 160/60-ZR17 rear tyre, a 15.5 litre fuel tank and a 195 kg dry weight. A Pioneer Powersports dealer listing corroborates the 6-speed gearbox, Brembo brakes with Bosch ABS, and KYB adjustable suspension.
The Moto Morini Seiemmezzo STR is a motorcycle from Moto Morini. It is currently on sale. With a 649 cc engine it sits in the middleweight 450–800 cc class.
Power comes from a 649 cc twin-cylinder engine that makes 59 HP at 8,250 rpm and 56 Nm of torque at 7,000 rpm. Its bore is wider than its stroke (83.0 x 60.0 mm), a short-stroke layout that generally favours higher revs. Divide power by kerb weight and it has about 307 PS per tonne; by that measure, it is genuinely fast, well beyond everyday traffic speeds. The claimed top speed is 180 km/h.
It has a 6-speed manual gearbox. It uses a wet multi-plate clutch.
It is built around a Cr-Mo steel alloy trellis / aluminium swingarm frame. Suspension is by KYB 43mm adjustable inverted forks at the front and KYB adjustable shock at the rear. Braking is by twin discs at the front and a disc at the rear. It rides on 18-inch front and 17-inch rear aluminium alloy, black wheels — 120/70-ZR18 at the front and 160/60-ZR17 at the rear.
The seat is 795 mm off the ground, which is about average and suits most riders. It weighs 195 kg ready to ride, which is on the heavy side, so moving it by hand takes some effort. Ground clearance is 170 mm — enough for most speed breakers. It is 2,150 mm long, with 1,440 mm between the axles. It carries 15.5 L of fuel.

Engine oil is the single most important consumable to keep fresh. Top up between services if the level drops, and change it on schedule.
With Double disc, 4-piston caliper, Brembo, ABS and Single disc, 2-piston caliper, Brembo, ABS brakes, check pad or shoe wear, lever and pedal free play, and braking feel at every service.
A clean, correctly tensioned and lubricated chain lasts longer and wastes less power. Check slack regularly, especially after riding in rain or dust.
A clogged air filter or worn spark plug shows up as hard starting, weak throttle response and poorer fuel economy. Both are checked at a regular service and replaced when worn.
Brake fluid absorbs moisture over time, which lowers its boiling point. Have its level and condition checked and change it on the interval in the owner's manual.
This bike runs 120/70-ZR18 / 160/60-ZR17 tyres. Check pressure, tread depth and sidewalls, and replace tyres that are worn or cracked.
Weak starting, dim lights or a flickering console are early signs the battery or charging system needs a look.
