The 2010 Honda CRF150R Expert is a motocross race bike with a 149 cc, liquid-cooled, four-stroke single-cylinder engine, carburetor, SOHC valve train and four valves. A kick starter and five-speed transmission suit closed-course riding, while the Expert’s big-wheel setup uses 19-inch front and 16-inch rear wheels. The steel frame is paired with a fully adjustable 37 mm inverted Showa fork offering 10.8 in of travel and a Pro-Link Showa rear shock with 11.1 in of travel. Seat height is 34.1 in, curb weight is 187 lb and fuel capacity is 1.14 gal. It is not street legal in the US.

Who it's for

This bike is for motocross racers and riders who practice on closed dirt tracks and want a small-displacement four-stroke race bike with big wheels. Its 34.1 in seat height and 187 lb curb weight are important fit considerations, especially for younger or shorter riders. The kick-start-only setup also suits riders prepared to start the bike by kick rather than electric starter. It is not a fit for street riding, commuting or anyone seeking a street-legal motorcycle.
