Most of my experience is with cruisers (last one was a 2012 Triumph Thunderbird 1600). Then in 2017 I switched to a '16 Yamaha FJR1300 sport-tourer and am now looking at switching to a new Ninja 1000 next year, the Spring of 2020, for something lighter and more nimble, more along the sport end of the sport-touring spectrum. There were several reasons why I switched, but the primary one was a bad lower back...the upright seating and leg-forward ergonomics of the cruiser means your tailbone acts an absorber and delivery system for any noteable bumps in the road, sending lightning bolts of pain up your spine if, as I did, you have a lower-back issue. I needed a slight forward lean and legs tucked under me in order to remedy that issue, but didn't want a significant forward lean ala a supersports bike with clip-ons. I wanted a bike that makes me look back after I park it and walk off, and the ADV segment wasn't going to give me that. I wanted some storage via hard panniers. All that said, the sport-touring segment was then the logical choice, and I'm glad I went that direction. In fact, I got pretty taken with the sportiness and handling of the FJR (as compared to the cruiser) and wanted even more of that, hence my plan to pick up the Ninja 1000 next year.
