Technical Overview
2018 Znen P9 II Technical Analysis & Specification Breakdown
At the heart of the 2018 Znen P9 II scooter motorcycle, Znen utilizes a 124.6 cc (7.6 cu in) single cylinder, four-stroke layout. In factory specification, peak output is rated at 7.2 HP (5.3 kW) at 7,500 rpm while maximum torque reaches 8.4 Nm (6.2 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 57.8 HP per liter and a 2,000 rpm working window between peak torque (5,500 rpm) and peak power (7,500 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the P9 II measures 104 kg (229 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (14.44 kg per horsepower). The 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 85 km/h (53 mph).
