Produced over a ten-year period between 1997 and 2007, the KTM 640 Adventure quickly became one of the most beloved dual-purpose adventure bikes on the market. This Jack of all trades machine is the ideal compromise between a large road bike and a small dirt bike. It sits in the middle, excelling at what it does.
This is THE bike to use to cross continents with poorer road surfaces. It will eat up any track and offers an incredible off-road experience. On the tar, it can feel a little buzzy, and after several hours of highway riding, you may be looking for something a bit bigger and comfier. However, on smaller side roads and city streets, the 640 Adventure is just as happy as when it’s in the dirt.
It’s certainly not the ideal bike for a beginner, as this 100% mechanical beast strips things back to basics. However, those with some off-road experience will soon tame the beast and never look back. It lacks all the mod cons of more modern adventure bikes, but what it lacks in features, it makes up for in unrivalled handling on poor surfaces.
Great for trips into second or third world countries and continents, but also a superb little commuter, the 640 Adventure offers something for everyone. Except long distance highway riders perhaps.

Common modifications on the KTM 640 Adventure
