At the heart of the 2011 Honda TRX300X atv motorcycle, Honda pairs a 282 cc (17.2 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 74.0 x 65.5 mm (2.9 x 2.6 inches) with a 12.0:1 compression ratio.
On the scales, the TRX300X measures 176 kg (388 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,143 mm (45 in) wheelbase engineered for quick, flickable steering geometry. The 8.33-liter (2.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
