At the heart of the 2007 Yamaha Majesty 400 scooter motorcycle, Yamaha pairs a 395 cc (24.1 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 83.0 x 73.0 mm (3.3 x 2.9 inches) with a 10.6:1 compression ratio.
On the scales, the Majesty 400 measures 196 kg (432 lbs) dry. Rider ergonomics and chassis geometry center around a 749 mm (29.5 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.
