Get thts Get that bla bla bla...
TEST RIDE until you find the one that speaks to you and fits!!!! That's the best advice you will ever get.
As far as HD is concerned they can suck it! After HD axed Buell I feel finished with them.
The only HD to get my vote would be the XR1200X Sportster. HD has perfected the air cooled unit construction 1200cc engine/transmission. Plenty of practice since 1957 on that one!!
