Engineered by Honda for the atv motorcycle segment, the 2021 Honda FourTrax Rancher features a 420 cc (25.6 cu in) liquid-cooled single cylinder, four-stroke configuration. Internal engine geometry specifies a bore and stroke of 86.5 x 71.5 mm (3.4 x 2.8 inches) with a 9.9:1 compression ratio.
On the scales, the FourTrax Rancher measures 263.1 kg (580 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 856 mm (33.7 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,270 mm (50 in) wheelbase engineered for quick, flickable steering geometry. The 14.76-liter (3.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
