From looking at the Parts Fiche for the frame it appears that the best place to make a bolt on is where both foot peg brackets bolt to the bike. It appears that mounting plates would have to sit between the brackets and the frame which will require longer bolts and possibly some spacers for the rear subframe support to line up correctly. This is similar to what DualStar does for mounting the DR and KLR on there center stands. It looks doable but will require a bit of work to get it right.
I sure like the looks of that bike, wish I had one.
Thanks for the answers to my question. I would be Leary of attaching a center stand to the skid plate mounts. It looks like a failure waiting to happen.
