Indeed, you did do a video on youtube. I very much enjoyed it and was kind of you to reply to questions asked. I liked your recording style and thoughts offered on the bike.
I am bit surprised we don't have any R18B owners on the site else none that wish to offer owner experience comments. Maybe a case of others happy with the bike and glad they got it

thus riding it and no time to post.
Likewise, like most things, ones option might not be the same as others thus maybe with any bike it is up to the rider to find if any given bike ridden its their idea of a sweet ride.
In the case of the R18B it is possible my eyes favor the bike more then my bodies ability to easily handle it. The gift of the heavy front end fairing seems to be a trait carried over from the r1200clc line. Well that plus I am only 5'9" and 210lbs +/- with 30" inseam.
When getting back from the demo ride I did not attempt to do a low speed close turn around and instead simply parked it in a space. Yes, it has reverse and could use that. Impressed with your low speed trun ability skills for certain.
Others, Adam has other videos on his site. One I think about vblooging...maybe a topic he presented at the recent bmw national rally. I have not listend to it yet but plan to.
Not R18 related though do wonder what bmw will do next with the r1250 line. Not certain I can see them jumping the shark and going up to a r18 engine. Simply seems too big for a touring frame r1250rt layout. Do like the new bmw thought on an electric motorcycle via via making it an 'opposed twin' loking layout design. Thinking though we are several years out before we get to buy one of those.
