Engineered by Znen for the scooter motorcycle segment, the 2016 Znen TBX 150 utilizes a 149 cc (9.1 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 8.1 HP (5.9 kW) at 8,000 rpm while maximum torque reaches 8.4 Nm (6.2 lb-ft) at 5,400 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 54.4 HP per liter and a 2,600 rpm working window between peak torque (5,400 rpm) and peak power (8,000 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the TBX 150 measures 130.2 kg (287 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (16.07 kg per horsepower). Rider ergonomics and chassis geometry center around a 762 mm (30 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops. The 9.46-liter (2.5 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 89 km/h (55 mph).
