Engineered by Yamaha for the atv motorcycle segment, the 2009 Yamaha Grizzly 350 Auto 4x4 features a 348 cc (21.2 cu in) oil & air-cooled single cylinder, four-stroke configuration. Internal engine geometry specifies a bore and stroke of 83.0 x 64.5 mm (3.3 x 2.5 inches) with a 9.2:1 compression ratio.
On the scales, the Grizzly 350 Auto 4x4 measures 243.1 kg (536 lbs) dry. Rider ergonomics and chassis geometry center around a 828 mm (32.6 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 14.38-liter (3.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
