Not trying to hijack the thread but since the Shinko Raven was already mentiond:
I've got a '99 R1100R that is the limited edition with the wire wheels. Same size wheels as the GS I believe.
The bike came to me with Dunlop Sportmax radials and the rear is in need of replacement.
I've been thinking about trying the Shinko Raven but they don't offer an exact match to the size that's currently on there. Current size is a 150/70-17 and the closest that I could get the Raven in is a 160/60-17.
Think it will work on this wheel and bike?
