I switched from a 2017 AT. It was a decent road bike and very good off road, but I’m much happier with my 2022 GS
I didn’t like dealing with tubed tires and it was using a bit of oil. It lacked power for aggressive road riding. I ride a lot of miles, 20,000+ a year and the valve checks were a PITA.
The GS is a far better road bike and still good off road. Maintenance intervals are a little shorter, but far easier to do. Overall I find the BMW to be higher quality, fit and finish. That’s compared to the 2017 Africa Twin, I haven’t ridden the newer models.
