Engineered by Honda for the atv motorcycle segment, the 2016 Honda TRX420TM1 utilizes a 420 cc (25.6 cu in) liquid-cooled single cylinder, four-stroke layout. 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 TRX420TM1 measures 261 kg (575 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 1,268 mm (49.9 in) wheelbase engineered for quick, flickable steering geometry. The 14.7-liter (3.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
