So far I tried :

HD street glide (old 1450 model)
BMW R1200RT
BMW R1200 GS
BMW K1600 GTL
And recently the Victory Cross country.

The HD is a great bike, but for cruising only.... (I had a Dyna before...I know HD quite well)
BMW RT, don't like the engine, but the bike is very comfortable, easy to ride, very versatile (town, road, highway, mountain road roads...).
K1600 engine is just amazing....maybe too much ! It's clearly more a sport bike than a road bike. I love it ! But I want you keep my driving licence.... :-)
Victory Cross country is better in all than HD : except engine feeling....in fact I was disillusioned when riding it.

Now I'm going to try a Ducati Diavel !!!
I also rode the Ducati Multistrada, the engine is amazing !! I just hated the drive position, that's why I'm going to try the Diavel.

I'm thinking of changing my F6B in fact...
