Ausfletch,
I did see one of the DRs, but it wasnt the 650. (sorry I didn't get the photos for you) Most everything was rented when I got there,,which is why I got the Yamaha. The only advice I guess is go with the flow,,don't get caught out after dark,,(like I did once). It was really pretty easy traveling around, but some of the roads are a little tricky and San Jose will give you some pucker factor.
As for Morten and Thorsten, they were very friendly. They will go over the bike with a fine tooth comb when you return. Morten tried to charge me (5dollars) for a turn signal lens that fell off the Yamaha. I wasn't going to make a big deal about it, but I did stress that I never went down on the bike and it simply fell off when on a paved road. He didn't charge me. I think they are okay guys. Morten invited me back again, so I guess he feels okay with me using their bikes.
