Built around Junak's allround motorcycle platform, the 2020 Junak M15 125 utilizes a 125 cc (7.6 cu in) liquid-cooled twin, four-stroke layout. In factory specification, peak output is rated at 19 HP (13.9 kW) at 9,500 rpm, transferring power to the rear wheel through shaft drive (cardan) final drive. With a specific output of 152 HP per liter, the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the M15 125 measures 188 kg (414 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (9.89 kg per horsepower). Rider ergonomics and chassis geometry center around a 720 mm (28.3 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops. The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 85 km/h (53 mph).
