K1600GT Conquest Against Goldwing and Ultra Glide
I agree with Don's comments. These bikes are not to cater to existing BMW owners, but to cannibalize the market for Interstate touring machines, like the Goldwing and the Harley Ultra Glide. The sure giveaway that the K1600GTL is designed to lure Goldwing and Ultra Glide buyers is if they put the "Barcalounger" seat on the pillion, complete with the compulsory armrests.
I ride solo myself, but I think that every Goldwing and Ultra Glide I have ever seen with a female pillion passenger has the "Barcalounger" seat with armrests. Some of them even have a cupholder attached. I understand that SWMBO's demand this feature on these bikes. They are regally seated, with hands clasped firmly around the each end of the armrests.
The closest I have seen on BMWs is the huge 49 liter topcase with the backrest pad. Female pillion passengers on this setup, lacking the armrests are left with no other alternative, but to grasp their thighs , as a resting place for their hands.
Armrests are a must!
