Which is the better BMW Sport Tourer - S1000XR vs R1250RS

[runnerhiker]

I wish BMW made a K1300RS with shaft drive and size and weight similar to my R1250RS.  An XR with a shaft drive won't do it, the "bucket" seat is just too bad, and the seat height is too high - two things that I could not fix on my XR.  Even though I had 3 seats for the XR including one Wunderlich seat that was further customized.
