2009 Nipponia NB 125E Technical Analysis & Specification Breakdown
At the heart of the 2009 Nipponia NB 125E sport motorcycle, Nipponia relies on a 124.8 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 10.1 HP (7.3 kW) at 9,000 rpm while maximum torque reaches 7.8 Nm (5.8 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and belt final drive. With a specific output of 80.9 HP per liter and a 1,000 rpm working window between peak torque (8,000 rpm) and peak power (9,000 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 NB 125E measures 120 kg (265 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (11.88 kg per horsepower). The 11-liter (2.9 US gal) fuel tank paired with a rated consumption of 2 L/100 km provides an estimated theoretical range of roughly 550 km (342 miles) between fill-ups, while factory top speed is listed at 120 km/h (75 mph).
