KTM makes great motorycles, but no bicycles. If you plan to ride in the woods go as light as possible unless you are a really heavy person. The 450 is the lightest on this list, and still has plenty of power for the road. But unless my knowledge of KTM models is out of date, none of these models are street legal.
For more input, it would serve you better to post this question under Cars & Transportation, Motorcycles.
