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 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 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.
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.
