The new Kawasaki Ridge XR is supposed to run 74 mph.
The Kawasaki Ridge Limited is supposed to rent 68 mph.
The defender and Ranger will run about 66-68 mph.

Just guessing but I think fuel consumption will also be worse on the ridge probably only would matter to farmers. As I never pay attention to that.

If you’re going to modify your machine the ridge is very attractive unit for that. It will perform better than the other two as it has more hp. It would take extensive effort to get that hp from a defender or ranger.
