Engineered by Znen for the scooter motorcycle segment, the 2014 Znen 150 Roar 4 pairs a 149.6 cc (9.1 cu in) single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 9.5 HP (6.9 kW) at 7,000 rpm while maximum torque reaches 9.6 Nm (7.1 lb-ft) at 5,500 rpm. With a specific output of 63.5 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 150 Roar 4 measures 148 kg (326 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (15.58 kg per horsepower). The 9.5-liter (2.5 US gal) fuel tank paired with a rated consumption of 2.9 L/100 km provides an estimated theoretical range of roughly 328 km (204 miles) between fill-ups, while factory top speed is listed at 95 km/h (59 mph).
