I have 2 friends that each have a 2007 R1200RT. I can't comfortably ride them due to the high seat. A short inseam and weak muscles and a top heavy bike does not work for many of us. Why does BMW insist on making most of their bikes with very hgh seats? I had both a K100RT and a K75RT and I was never comfortable with them due to the high seat (I lowered as much as possible) and top heaviness of the bikes. I then got a R80RT that was still relatively high but the weight and top heaviness was better. I added a R1200 CLC that worked much better with the lower seat but they discontinued it.
I think cruisers have their large market share because of the lower seat height that allows people of limited stature and smaller people (height and strength) to ride more easily.
I like BMWs and want to continue to ride them but I may wait a long time or never upgrade unless BMW changes their bikes (BMWs have driveshafts and boxer motors-others are BMWs in name only).
