Built around Yamaha's scooter motorcycle platform, the 2008 Yamaha Morphous utilizes a 250 cc (15.3 cu in) liquid-cooled single cylinder, four-stroke layout. Internal engine geometry specifies a bore and stroke of 66.0 x 73.0 mm (2.6 x 2.9 inches) with a 10.8:1 compression ratio.
On the scales, the Morphous measures 185.1 kg (408 lbs) dry. Rider ergonomics and chassis geometry center around a 655 mm (25.8 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,615 mm (63.6 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.
