At the heart of the 2023 Orcal NK01 125 allround motorcycle, Orcal utilizes a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 9.1 HP (6.7 kW) at 8,500 rpm while maximum torque reaches 9.4 Nm (6.9 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 72.8 HP per liter and a 3,500 rpm working window between peak torque (5,000 rpm) and peak power (8,500 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 NK01 125 measures 126 kg (278 lbs) wet (curb), translating to a power-to-weight ratio of 0.07 HP/kg (13.85 kg per horsepower). Rider ergonomics and chassis geometry center around a 755 mm (29.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,350 mm (53.1 in) wheelbase engineered for quick, flickable steering geometry. The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
