The 2011 Honda CRF150R is a motocross race bike with a 149 cc liquid-cooled, four-stroke SOHC single-cylinder engine, four valves and carburetor fuel delivery. It has a five-speed transmission, cable-operated wet multiplate clutch and kick start. A steel semi-double-cradle frame carries a 37 mm inverted Showa fork with adjustable compression and rebound damping, plus a Pro-Link rear suspension with a single Showa damper. Suspension travel is 10.8 in up front and 10.7 in at the rear. The 32.8 in seat height, 17-inch front wheel and 14-inch rear wheel distinguish this standard-wheel model from the CRF150R Expert. Fuel capacity is 1.14 gal, and the factory color is Extreme Red.

Who it's for

This CRF150R is for motocross racers who want a compact, standard-wheel race bike with a 32.8 in seat and 17-inch front and 14-inch rear wheels. Its race-focused category and equipment suit track riding rather than trail use. Riders choosing between it and the CRF150R Expert should consider the wheel and seat dimensions: the standard model has smaller wheels and a lower seat, while the Expert has larger wheels and a taller seat.
