Built around Honda's atv motorcycle platform, the 2018 Honda FourTrax Foreman Rubicon 4x4 pairs a 499 cc (30.5 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 92.0 x 71.5 mm (3.6 x 2.8 inches).
On the scales, the FourTrax Foreman Rubicon 4x4 measures 313 kg (690 lbs) dry. Rider ergonomics and chassis geometry center around a 861 mm (33.9 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,285 mm (50.6 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.
