At the heart of the 2015 Yamaha X-MAX 125 MOMODesign scooter motorcycle, Yamaha pairs a 124.7 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 14.2 HP (10.3 kW) at 9,000 rpm while maximum torque reaches 11.9 Nm (8.8 lb-ft) at 6,750 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 113.9 HP per liter and a 2,250 rpm working window between peak torque (6,750 rpm) and peak power (9,000 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the X-MAX 125 MOMODesign measures 169 kg (373 lbs) wet (curb), translating to a power-to-weight ratio of 0.08 HP/kg (11.9 kg per horsepower). Rider ergonomics and chassis geometry center around a 792 mm (31.2 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,525 mm (60 in) wheelbase engineered for planted straight-line stability. The 11.8-liter (3.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
