Hello Andy. Welcome.
I moved from a GSF650S (via a GSX1250) to a 2017 DL650 and am very pleased with it. The most immediate difference I noticed was the powerful engine braking, making it much easier to ride "on the throttle". Although the 650 Bandit had more horsepower, it needed spinning up to find it, whereas the V-Strom pulls strongly all the way from low revs and the wide bars make more responsive to hustle in the twisties. The mpg and accompanying range make it great at touring.
On the downside (there's always one), I found the seat too high and even with the Suzuki lower seat it has taken me a while to adjust. But that's short legs, as issued, for Your.
Hope you enjoy your new bike as much as I do.
