The Honda CRF150R is a racing motocross bike that was released in 2006 for the 2007 model year. It competes in the Mini Class against many 85 cc (5.2 cu in) two-stroke bikes; however, it cannot race in the 85cc mod. or stock class. It must race in the Supermini class.[1] All of Honda's 2008 models are four-strokes whereas in years past, some of their racing bikes were two-strokes. The 150R features a powerful Unicam four-valve liquid-cooled engine that produces impressive power at a wide RPM range. And only weighs 185 pounds wet (which means with fluid's) . With its fully adjustable Showa suspension, high-quality Dunlop Tires and disc brakes front and rear, this is one of the best mini racing bikes Honda has made. The CRF150R come in two versions: the regular and the Expert.

The Expert costs an extra $100 and offering several new features specifically for larger riders. Features include a taller seat height, higher ground clearance, larger wheelbase, increased tire size, longer swing arm and larger rear sprocket for better acceleration with a heavier rider. All of these Expert features only add an additional 4 pounds. This model is referred to as the CRF150RB R meaning Race, and B meaning Big wheel.
