KTM 400 Enduro Motorcycle - Dual-Sport (1976-2001)

The KTM 400 Enduro, produced from 1976 to 2001, represents a significant evolution in off-road motorcycles. Initially a two-stroke machine, it transitioned through various engine configurations and frame designs, culminating in the four-stroke LC4 and EXC models. The "400" designation often referred to a class rather than exact displacement, which varied across its production run. The early models (1976-1979) were two-stroke, with actual displacements around 359cc, and saw frame updates from MC-5/GS-6 to MC80/GS80. A period of shifting engine sizes followed, with the 400cc two-stroke reappearing around 1987-1990 with a 344cc engine. From 1994 onwards, the 400 Enduro predominantly featured 398cc four-stroke LC4 engines, later incorporating the advanced Racing Four-Stroke (RFS) engine design in 1999, marking a major technological shift.
