Positioned in Yamaha's scooter motorcycle lineup, the 2009 Yamaha Majesty 400 ABS utilizes a 395 cc (24.1 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 33.5 HP (24.5 kW) at 7,000 rpm while maximum torque reaches 36.3 Nm (26.8 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 84.8 HP per liter and a 1,000 rpm working window between peak torque (6,000 rpm) and peak power (7,000 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 Majesty 400 ABS measures 220 kg (485 lbs) wet (curb), translating to a power-to-weight ratio of 0.15 HP/kg (6.57 kg per horsepower). Rider ergonomics and chassis geometry center around a 760 mm (29.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,565 mm (61.6 in) wheelbase engineered for planted straight-line stability. The 14-liter (3.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
