Positioned in Yamaha's atv motorcycle lineup, the 2009 Yamaha Wolverine 450 Auto 4x4 relies on a 421 cc (25.7 cu in) liquid-cooled single cylinder, four-stroke powerplant. 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 Wolverine 450 Auto 4x4 measures 234.1 kg (516 lbs) dry. 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 14.38-liter (3.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
