1994 KTM 620 Specifications

1994 was the first year KTM offered a 620 cc motorcycle. The bike came in two variations: the Duke was a pure street bike, and the LC4 was a dual-sport dirt bike. A dual-sport bike has off-road capabilities, but is also street-legal. The 1996 LC4 620 Adventure was an upgraded version of the LC4 dual-sport bike. KTM produced a 620 motorcycle until 1998.
