KLR650. I wanted to like it, I really did. I have some friends who have them and love them, but it just didn't work for me. The thing was incredibly big, heavy and tall. Really top heavy even with an empty gas tank. If it leaned over more than about 2 degrees before I got a foot down, that bike was going DOWN! I dropped it once in my garage and had to have a friend come over and help me pick it up.
Also it tended to run the battery dead for no apparent reason. I tried three batteries and concluded that wasn't it. The charging system seemed to check out ok, but the battery would just go dead sometimes. I was out on a ride one time, bike was running great all day, stopped to take a photo. Pushed the magic button when I was ready to go - click click click. Had to have a friend come rescue me with his truck. Another time I was going to ride it to work but the battery was dead. I'd just ridden it the day before and all was well. Never did figure it out.
I was never happier to see a bike go away....
