Engineered by Italjet for the scooter motorcycle segment, the 2008 Italjet Jupiter 250 relies on a 249.8 cc (15.2 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 20.8 HP (15.2 kW) while maximum torque reaches 19.9 Nm (14.7 lb-ft), transferring power to the rear wheel through a automatic gearbox. With a specific output of 83.3 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Jupiter 250 measures 156 kg (344 lbs) dry, translating to a power-to-weight ratio of 0.13 HP/kg (7.5 kg per horsepower). Rider ergonomics and chassis geometry center around a 730 mm (28.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops. The 12.5-liter (3.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
