Technical Overview
2025 Znen Tank II Technical Analysis & Specification Breakdown
At the heart of the 2025 Znen Tank II scooter motorcycle, Znen features a 150 cc (9.2 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 10.2 HP (7.4 kW) at 7,500 rpm while maximum torque reaches 10.1 Nm (7.4 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 68 HP per liter and a 1,500 rpm working window between peak torque (6,000 rpm) and peak power (7,500 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 Tank II measures 125 kg (276 lbs) wet (curb), translating to a power-to-weight ratio of 0.08 HP/kg (12.25 kg per horsepower). Rider ergonomics and chassis geometry center around a 760 mm (29.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,310 mm (51.6 in) wheelbase engineered for quick, flickable steering geometry. The 7.4-liter (2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 90 km/h (56 mph).
