Built around Yamaha's atv motorcycle platform, the 2020 Yamaha Raptor 90 utilizes a 89.9 cc (5.5 cu in) air-cooled single cylinder, four-stroke layout. Internal engine geometry specifies a bore and stroke of 47.0 x 51.8 mm (1.9 x 2.0 inches) with a 9.2:1 compression ratio.
On the scales, the Raptor 90 measures 126.5 kg (279 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 750 mm (29.5 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops. The 6.6-liter (1.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
