Since 1979, Honda has led the way in the realm of off-road dirt-bike-style motorcycles. The Honda XR 185, XR 250, and XR 500, along with other popular models, all provided power, durability, and style to dirt bike enthusiasts. In 1982 and 1992, Honda released the XR 600 series. These bikes proved extremely popular, especially after desert racers Johnny Campbell and Scott Summers won several Baja races on their XR 600s. In the year 2000, Honda released the XR 650 as a replacement in the line-up for the XR 600. However, Honda did more than simply update the 600 series. The Honda 650R was a completely redesigned motorcycle with a unique frame and a brand new, liquid-cooled, four-stroke engine. The Honda XR 650L, on the other hand, is quite different from the 650R. In fact, the 650L is more similar in style and function to the XR 600. Honda designed the 650R for racing, while the XR 600L is a dual-purpose machine that was made for off-road or city driving.
