I had the same experience with the same bike. 3 weeks after I bought it- "testing" it out in the canyons-
Then a year later after just finishing a canyon heading back to town-
Finally sold the bike, but I want it back incredibly bad. It puts out the same power as the DR650 but is quite a bit lighter.
I should note both times were totally my fault. Although I could blame it on bad tires both times....
