It's a timely thing for this thread to pop up, as I have had my 2022 R18B for a few weeks now and I am having difficulty in framing up my satisfaction with the bike in comparison to my other primary bike, my 2020 R1250GSA.
I have had GS bikes for the past decade and have ridden them all over the Southwest as well as renting them for trips from Portland to Alaska, and just recently a two-week trip touring much of Germany, Austria, and Switzerland.

The GS bikes are really a good all-arounder, and I thought it would be a nice addition to the stable to add an R18B now that they are getting discounted by so much. I bought mine out of Las Vegas and while that was a slight disaster with that dealership, I am working to try to frame up my experiences with my R18B as not a comparison to my GSA, but as a comparison to the R18B's main competitors.
I have the luxury of having a good friend who is the GM of a large Harley dealership here in Phoenix and like most HD dealers he is happy to give you the ability to do fairly lengthy test rides of nearly everything. For years, I have gone out once a year and have taken an hour-long ride on either a Street Glide with him coming along on another bike, or on a Road Glide. After doing this for a number of times and also after renting a few Street Glides I was happy to see BMW come out with an equivalent bike, as I have always felt that the HD counterparts are really needlessly heavy and have serious deficiencies when it comes to braking and handling, in comparison to what I am used to riding.
So, long story short I decided to make a deal on my 2022 R18B as it was being sold as "used but with remaining warranty with 2 miles on it" and flew to Vegas on a pretty hot day to ride it back to Phoenix. First off, the shifter and the brake pedal were way out of adjustment and that has a ton to do with how the bike feels and how you connect to it. Secondly, there's the case of wind noise and buffeting which we all have to figure out on our own, as that is a very personal preference when it comes to windshields, deflectors and seat height. The R18 platform is still in its' infancy so at this point, there are only a few options that you can choose from.
When I got the bike home, I decided to make those adjustments as well as install a temporary windscreen deflector that I bought from Amazon to see if I could make a bit more peace with the bike. I also started to dig into the aftermarket to find a few things to feel a bit more at home than I did on the ride home. The big upsides to the bike are the vastly better TFT integration into your cell phone and headset vs the GS/A platform, so that is a big plus for the bike. As I have made those adjustments, done my own 600-mile service and adjusted the valves, and played with a few more things, the bike has started to endear itself to me a bit more.
I think that in time I will enjoy the bike more, especially when I frame it in a different light to my GSA. The GSA has a ton more suspension travel, much better braking characteristics and a ton more power, mostly because of the power to weight ratio but also as the GSA has a 40 horsepower difference. I think that the more apt comparison here is to the Street Glide and Road Glide platforms, and to that I think that you can make a better case for the R18 platform. It will be more difficult to find aftermarket parts for it, but in the end I think the build quality and material quality and engineering that went into the BMW is far better than the HD equivalent.
Those are my two cents, for what they are worth. I am going to stick with it and see if I can solve a few issues and just enjoy it in the frame of reference that suits it.
