Engineered by Yamaha for the atv motorcycle segment, the 2017 Yamaha Grizzly 450 EPS features a 421 cc (25.7 cu in) liquid-cooled single cylinder, four-stroke configuration. Internal engine geometry specifies a bore and stroke of 84.5 x 75.0 mm (3.3 x 3.0 inches) with a 10.0:1 compression ratio.
On the scales, the Grizzly 450 EPS measures 281.2 kg (620 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 841 mm (33.1 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,232 mm (48.5 in) wheelbase engineered for quick, flickable steering geometry. The 15.14-liter (4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
