Vehicle Information
KTM 400 EXC Dirt Bike (1993-2011)
The KTM 400 EXC, produced from 1993 to 2011, is a renowned enduro motorcycle known for its robust performance and off-road capabilities. Over its long production run, this 400cc four-stroke model saw significant evolution in its engine and chassis. The early models (1993-1998) featured the LC4 engine, appearing under designations like LC4 EXC, LC4 EGS, and EGS-E. From 2000 to 2007, the 400 EXC was powered by the acclaimed "Racing Four Stroke" (RFS) engine, which introduced electric start and underwent several chassis updates, including a new subframe and airbox in 2003, and a new frame between 2005-2007. The final generation, from 2008 to 2011, saw the introduction of the XC4 engine and another new chassis design, with continuous refinements and the availability of "Six Days" special editions. These distinct engine and chassis platforms mark clear generational shifts. FAQ:
