Lol, fast is nice, but my favorite bikes are smaller. My 125 scooter is my current favorite if I don’t need to go above 50mph, and I sorely miss my ninja400. As for the comfortable issue with cruisers, it’s supposedly an issue because of the leaned back, pressure-on-tailbone seating position. Neutral (upright) seems to be the most comfortable for the majority, and you know what’s king of those right now? ADVs ;) They’re basically the luxury bikes right now, with all the fancy electronics on the newer models, lots of suspension, and fast enough to do anything highway/street. Your goldwing types might technically be plushier, but ADVs are popular for a reason.
I have a supersport-lite: an older sport tourer with waaaay too big of an engine for what I want to do with it, but unless you find yourself acting silly now, you won’t have much to worry about. The occasional urge to catch that stupid muscle car blowing past with an exhaust tuned to sound loud passes you by just as quickly as you pass them by…
