I had the same problem when mine was new. When i hit grooved pavement, or road seams, or any kind of sand it would seem as if the bike was twisting and it really scared me. I kept reading about how great the DR650 was, so I just figured it was my poor riding abilities.
When I went to change my first tire I found that the swingarm bushings were completely wasted - had less than 4000 miles on it. Had them replaced under warranty. After they were replaced the "frame flex" problem went away completely.
Now I've gone from riding a Flexy Flyer to a Sexy Flyer hahaha!
