Engineered by Honda for the atv motorcycle segment, the 2011 Honda TRX420FA 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).
On the scales, the TRX420FA measures 282.6 kg (623 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 823 mm (32.4 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,255 mm (49.4 in) wheelbase engineered for quick, flickable steering geometry. The 13.24-liter (3.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
