In the 2011 Honda CRF 250R, a 249-cc Unicam engine with battery-less fuel injection delivers great performance. In fact, the 250R is one of the most popular and successful 250-cc dirt bikes used in track racing. The split engine design allows engine and transmission oil to be separated. This, along with the high build quality typical of Honda helps keep the company’s reputation for durability and value. The braking system of the 2011 Honda CRF 250R is particularly useful because the bike is one of the lightest in the class and the wave-style rotor stop it in an instant. This, of course, is expected from a Honda bike.
