Ugly.
Somebody told me that BMW design their motorbikes using "Kriegsmarine manual to design U-Boots" from II-nd WW.
And it's true. This motorbike is confirmation.
I looked hard at the K1600 before buying my F6B. The appeal is certainly there with it's classy controls and 160 hp.
In the end, I paid 1/2 the price and got a super reliable and fast motorcycle in the F6B. My Honda has plenty of power for me and I find myself using most of it on occasion.
I don't ride motorcycles for the controls glitz or top end mph. I prefer the "old school" controls and simply enjoy listening to the engine cut the wind. When I pass vehicles on the interstate, it happens fast. I love that !!
