Neat setup for touring. That type of setup was real common when I got into the BMW rally scene in the mid 80's. Still see alot of them at rallies today. I had a 74 R90 set up very simular, and toured thousands of miles that way. I'ts now apart undergoing a ground up resto. There was a BMW shop in Ft. Smith, AR. called Danny's, back in the 70's and 80's, who set up R100RTs and Ts just like that. We called them Danny's Specials and I still see them around the Ar, Ok, ,and Tx. area rallies. Good luck with your new ride.
Hey Barry, be sure to post pics of your R90's progress, especially before and after shots if you've got any.
