Built around Nipponia's naked motorcycle platform, the 2021 Nipponia Duel 125 relies on a 124.9 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 9.8 HP (7.2 kW) at 8,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 78.5 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Duel 125 measures 135 kg (298 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (13.78 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. The 9-liter (2.4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 90 km/h (56 mph).
