Seems like you have a pretty good spread of bikes right now. I have owned too many D/S bikes, in the last several yrs, trying to find that one
special bike. I think you have narrowed it down to two of the best lighter
D/S bikes available. I would vote for the 500. I owned a 08 530, which was extremely capable off road, and tolerable on slab. Not as comfy as a
klr on the road. Being that you have a tiger, get the lightest bike available, which would probably be the KTM500. Gives you a big difference between the two. One bike that I really liked was an 06 Husky TE 610. It still was not as light and powerful as the KTM, which made it
a little more challenging off road. Anyway good luck. Always fun getting a new bike.
