Built around Diamo's scooter motorcycle platform, the 2008 Diamo Retro 150 relies on a 150 cc (9.2 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 10 HP (7.3 kW), transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 66.7 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
Rider ergonomics and chassis geometry center around a 737 mm (29 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,270 mm (50 in) wheelbase engineered for quick, flickable steering geometry. The 7.57-liter (2 US gal) fuel tank paired with a rated consumption of 3.01 L/100 km provides an estimated theoretical range of roughly 251 km (156 miles) between fill-ups, while factory top speed is listed at 89 km/h (55 mph).
