Engineered by Yamaha for the atv motorcycle segment, the 2011 Yamaha Raptor 90 utilizes a 88 cc (5.4 cu in) air-cooled single cylinder, four-stroke layout. Internal engine geometry specifies a bore and stroke of 47.0 x 51.0 mm (1.9 x 2.0 inches) with a 10.2:1 compression ratio.
On the scales, the Raptor 90 measures 119.8 kg (264 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 653 mm (25.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops. The 4.92-liter (1.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
