I came this close ->|<- to buying a 2013 R1200RT. Despite the lovely accessory overload on the Beemer, the quality of build materials, and that I have been a long time BMW owner/rider, I had second thoughts on BMW's reputation for poor reliability and customer service these last few years so I went with the Honda F6B. 180 degrees for me.
Not just saying because I bought one, but boy am I glad I chose the F6B over the Beemer. These machines are at their Zenith for reliability and run like a locomotive.
Honda should have named this beast the GL1800ST
Of course your mileage may vary. Best of luck with your decision.
