KTM did what it does best with its EXC line of motorcycles. The Austrian manufacturer is one of the leading makers of off-road bikes, whether for recreational or racing purposes. KTM riders have racked up more than 130 championships in off-road competitions since the 1990s. This tradition continues with the EXC models, from a 125 cc two-stroke to the model 530 (510 cc) four-stroke. KTM introduced the EXC line in 2007. By 2010, KTM was offering eight models in this line: 125, 200, 250, 250 EXC-F, 300, 400, 450, and 530. These motorcycles are classified as Enduros, but they’re not really made for street riding, though they are street legal with a headlight, taillights, turn signals, street-legal tires and both bike and rider need to be licensed. These KTM dirt bikes are fully certified by the U.S. Department of Transportation. Having this equipment on a dirt bike allows riders to get around government rules that prohibit non-street legal bikes on government roads such as forest roads when dirt bikers are moving from one trail to another. The EXC line also is made for off-road racing such as motocross, with racers generally removing the mirrors before taking to the track.
