Built around Yamaha's atv motorcycle platform, the 2020 Yamaha Kodiak 450 EPS 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 Kodiak 450 EPS measures 295 kg (650 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 855 mm (33.7 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,240 mm (48.8 in) wheelbase engineered for quick, flickable steering geometry. The 14-liter (3.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
