For what it's worth, I too started out in the "club" and dove in head first. I had my official vest, chaps, brain bucket and all the other trimmings. A test ride of the R1200RT 15 years ago was my first step to recovery. More than once, I've talked to Harley people standing over and staring at my parked GTL like it was an alien space ship. The divide between the two worlds is fascinating. All I can say is I'm glad that I crossed it.
I am finding more of the Harley guys are really starting to give the BMWs and Goldwings more serious looks now, as compared to 10-20 years ago, but this is the aging crowd of your typical "Harley Guy" and may be some realization that there are good bikes out there outside of Harley's spectrum
As far as the original post was fishing for, I bought the manual on CD that seems to be a copy of the dealer manual. That thing reads like a Chinese calculus equation for time travel. while all the information you need is there, it is not at all user friendly and takes a while to figure out for a first time user. But it is nice to be able to print yourself a page to walk out to the shop with and not worry about greasing up a $100 shop manual. But TBH, I have gotten more information from this forum and YouTube, along with the tips and tricks that make life a lot easier on yourself. Case and point: Xenon headlight bulb replacement. Found out on the forum here that you can access the headlight cover and change the bulb by simply taking the handlebars off, as compared to a surgical procedure that would have taken half the day, that otherwise the shop charges close to $500 for to change a bulb that costs $60 on Amazon...
The stereo speakers suck, and there have been folks that have put some real money into their bikes to get something decent with them. Just use the Bluetooth, its better anyway. But the stereo/Bluetooth isn't that great either and there are also fixes for that as well, which have also been discussed in the forum.
Used bikes are about to get cheaper with the offseason, and the 2019 stock is starting to go into discount mode, especially at large dealerships. Consider this vs. waiting until the riding season gets started next year when everything goes into profit mode and prices go back up in the spring.
