Positioned in Honda's cross - motocross motorcycle lineup, the 2015 Honda CRF150R relies on a 149 cc (9.1 cu in) liquid-cooled single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 66.0 x 43.7 mm (2.6 x 1.7 inches) with a 11.7:1 compression ratio.
On the scales, the CRF150R measures 83.9 kg (185 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 833 mm (32.8 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,260 mm (49.6 in) wheelbase engineered for quick, flickable steering geometry. The 4.2-liter (1.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
