At the heart of the 2023 California Scooter SG250 Cafe Racer allround motorcycle, California Scooter features a 229.5 cc (14 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 16.1 HP (11.8 kW) at 7,000 rpm while maximum torque reaches 18.3 Nm (13.5 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 70.2 HP per liter and a 1,500 rpm working window between peak torque (5,500 rpm) and peak power (7,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the SG250 Cafe Racer measures 123.8 kg (273 lbs) dry, translating to a power-to-weight ratio of 0.13 HP/kg (7.69 kg per horsepower). Rider ergonomics and chassis geometry center around a 660 mm (26 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,290 mm (50.8 in) wheelbase engineered for quick, flickable steering geometry. The 15.14-liter (4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 109 km/h (68 mph).
