Built around Jonway's sport motorcycle platform, the 2008 Jonway YY150-2 relies on a 150 cc (9.2 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 8.4 HP (6.1 kW) at 7,500 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 56 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the YY150-2 measures 130 kg (287 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (15.48 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,425 mm (56.1 in) wheelbase engineered for balanced agility and highway composure. The 6-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 95 km/h (59 mph).
