At the heart of the 2021 Mh NKZ 125 naked motorcycle, Mh utilizes a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 11 HP (8 kW) at 9,000 rpm while maximum torque reaches 9 Nm (6.6 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 88 HP per liter and a 1,500 rpm working window between peak torque (7,500 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 NKZ 125 measures 118 kg (260 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (10.73 kg per horsepower). Rider ergonomics and chassis geometry center around a 777 mm (30.6 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,310 mm (51.6 in) wheelbase engineered for quick, flickable steering geometry. The 18-liter (4.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
