Positioned in Honda's atv motorcycle lineup, the 2013 Honda TRX400X utilizes a 397 cc (24.2 cu in) air-cooled single cylinder, four-stroke layout. Internal engine geometry specifies a bore and stroke of 85.0 x 70.0 mm (3.3 x 2.8 inches) with a 12.0:1 compression ratio.
On the scales, the TRX400X measures 185.1 kg (408 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 836 mm (32.9 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,217 mm (47.9 in) wheelbase engineered for quick, flickable steering geometry. The 9.84-liter (2.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
