The KTM Duke series is a family of standard motorcycles manufactured by KTM and Bajaj Auto Limited since from 1994. KTM is known for its off-road motorcycles (enduro, motocross and supermoto). Since the late 1990s, it has expanded into street motorcycle production and developing sports cars – namely the X-Bow. In 2015, KTM sold almost as many street as off-road bikes, so they’re naturally hyper and active and curious.
