The Honda CRF150R is a racing dirtbike that was released in 2006 for the 2007 model year. It competes in the Mini Class against many 85cc Two-Stroke Bikes; however, can not race in the 85cc mod. or stock class. It must race in the Supermini class [1]. All of Honda's 2008 models are all four strokes where as 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 that only weighs 43.6 pounds. 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. MSRP is $4,199 and $4,299 for the Expert.

All of these Expert features only add an additional 4 pounds. This model is referred to as the CRF150RB meaning R for Race and B for Big.
