At the heart of the 2013 Znen Bomb scooter motorcycle, Znen 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 8.5 HP (6.2 kW) at 7,500 rpm while maximum torque reaches 9.2 Nm (6.8 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 56.8 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 Bomb measures 105 kg (231 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (12.35 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,290 mm (50.8 in) wheelbase engineered for quick, flickable steering geometry.
