For purposes of the pricing discussion, I’m saying an Ultra Glide vs a GW with the touring trunk, or. BMW K1600. You could say that the GW and the K1600 have six cylinder engines. Also, you have to say that the newer HD V-twins have plenty of power for two up touring. Maybe not so much in the Evo era, but the new ones with the liquid cooled heads are more than sufficient.
HD has plenty of problems, but I think at least for the touring bikes ( Road Glide, Street Glide, Ultra) price is not an issue.
I’m not a HD rider, but I see what people like about them.
