The boxer engine always intrigued me, for decades since I was a kid. Im glad to see a full line from BMW = competition for Harley and Indian, though they are all priced similar.
Im without question a touring frame guy but not a fairing person. So I would vote to ride the R18 Classic. Though it looks like HD is the bargain with the Road King. Weight is also a concern with these monster touring bikes but I can see the R18 Classic and Road King are about the same.
I have been at times tempted by fairings for a "change" without seeing the BMW in person it wouldnt be fair to say this but I think I would be more tempted by Harley because of price and I would go for a more stripped down fairing bike which Hd offers the "standard". Ill admit I am the odd man out on this. Man I just want the lightest touring bike in a family of touring bikes AKA Road King, R18 Classic and Indian Springfield.
AS far as the bikes in the OP. Im not turned on by tons of electronics on a bike, I use the bike to get away from it all so the fairing displays mean nothing to me, The color choice is a turn off for me as well, that would be a lot of money to look at a bike I wouldnt enjoy looking at.
There maybe one more concern as far as a long range cruiser on the BMW, a 1500 mile test by one mentions the jugs in the way to stretch out your legs though I am sure anything is fixable and I guess I will never own a bike over $30,000 never mind a stripped down version over $23,000 ... maybe I am just getting old
but I look at the R18 Transcontinental and like any $30,000 bike I guess, I just see a bike that is gordy, fat and heavy.
At least in the photos. Now it would be a different story for me if side by side were the R18 Classic, Road King Standard and Indian Springfield. Its amazes me that the Harley is priced almost lower them them all, though you will be able to discount the others I am sure.
I am sure I am not the person BMW is marketing the Transcontinental too... *L*
