A lot of reading here to be done. Depends on why you are interested in the AT and which flavor; DCT or manual. So far I really enjoy mine (2018 AT adventure sport DCT) but not a fan of the tube type tires. Already had 2 flats in less than 600 miles. So plan to go tubeless soon.
Bike rides well, good power but wouldn't mind about 20hp more. The DCT is an awesome option. I can manually shift it or let it be fully auto. Traction control works well and easy to disable.
Wind protection is ok but need a better windscreen. The stock LED headlights are excellent. Fuel economy is great and with the 6+ gallon tank I can go over 300 miles without refueling. Seat is pretty comfy so far so no major complaints.
If you never plan on going offroad much better, or at all, there are better bikes (BMW S100XR, Ducati Multistrada are superior road bikes) but if you want to do some trails to it will do a pretty good job there as well. Keep in mind a 500 pound dirtbike is a pig to left if it falls at the end of a long riding day.
Lastly for the money you can pick up a leftover one they are a screaming bargain. At least in my area. A lot of bike for the money and typical Honda quality.
