Engineered by ShineTime for the allround motorcycle segment, the 2012 ShineTime Ace 50 features a 49.5 cc (3 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 3.1 HP (2.2 kW) at 7,500 rpm while maximum torque reaches 2.9 Nm (2.1 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 39.0 x 39.0 mm (1.5 x 1.5 inches) with a 9.0:1 compression ratio.
On the scales, the Ace 50 measures 78 kg (172 lbs) dry. Rider ergonomics and chassis geometry center around a 740 mm (29.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,075 mm (42.3 in) wheelbase engineered for quick, flickable steering geometry. The 5.5-liter (1.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
