Built around MBK's scooter motorcycle platform, the 2005 MBK Skyliner 125 pairs a 124 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 11.4 HP (8.3 kW) at 9,000 rpm while maximum torque reaches 9.4 Nm (6.9 lb-ft) at 8,500 rpm, transferring power to the rear wheel through a 6-speed gearbox. With a specific output of 91.9 HP per liter and a 500 rpm working window between peak torque (8,500 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 Skyliner 125 measures 134 kg (295 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.75 kg per horsepower). Rider ergonomics and chassis geometry center around a 774 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,480 mm (58.3 in) wheelbase engineered for balanced agility and highway composure. The 6.5-liter (1.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
