Engineered by MBK for the scooter motorcycle segment, the 2004 MBK FlameX utilizes a 124.8 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 8,500 rpm while maximum torque reaches 9.6 Nm (7.1 lb-ft) at 7,500 rpm. With a specific output of 88.1 HP per liter and a 1,000 rpm working window between peak torque (7,500 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 FlameX measures 114 kg (251 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (10.36 kg per horsepower). Rider ergonomics and chassis geometry center around a 770 mm (30.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,290 mm (50.8 in) wheelbase engineered for quick, flickable steering geometry. The 7.1-liter (1.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
