The KTM 640 Adventure is a dual-sport motorcycle made by KTM from 1998 until 2007.

The bike featured a single cylinder engine, 21" front and 18" rear wheels and a large fuel tank as standard. It experienced a number of minor changes over its lifespan.

In 1996 KTM introduced the 620 Adventure with a 609 cc engine. The bike received a new 625 cc engine for the 1998 model and was renamed the 640 Adventure-R.

For model year 2004 it experienced noticeable changes with a low front fender, twin front brake discs and the primary color changing from silver to orange.

Production ceased at the end of the 2007 after no further displacement changes.
