KTM introduced its XC line of motorcycles to the United States in 2006, where the line quickly became a favorite with dirt bikers and motocross racers. The Austrian manufacturer is the top European bike manufacturer as well as one of the world’s top makers of motorcycles. It is best known for making dirt bikes. Models in the 2010 line-up are the XC 150, XC 200 W, XC 250, XC 250 W, XC 250 FW Champions Edition, XC 300, XC 300 W, XC 400 W, XC 450 W Champions Edition, XC 450 W Six Days, and XC 530 W Six Days. The ""W"" in the model names stands for wide ratio transmission, which is better for desert and Enduro-type riding. Accessories for XC line include adjustable footpegs, assorted styles of aluminum skid plates, assorted graphics kits, tank pad set, assorted colors of spoilers, and higher or lower seats.
KTM introduced the XC 150 model, which has been described as an ""overzealous 125,"" in 2009, while the XC 250 was introduced in 2006. The XC 150 is the only bike in this line that does not have an electric start. The XC 150, which replaced the XC 200, is the size of a 125 cc bike, but has enough power to make riders feel like they‘re on a 250 cc. In other models, this is the first year for the XC 250 F W Champions Edition, which is comparable to KTM's official motocross racing team bike. The XC 300 has an electric start; motocross racers are apt to get in 200 hours of riding between services. The XC 300 also comes with an electronic odometer that allows Enduro racers to keep time. Reviewers say the XC 300 will easily beat the motocross competition in age or ladies’ class races when there is no displacement rule.
