Couldn't agree more. Tha GW currently states 35 mpg and get about 40 on the road. This one states 42mpg, so I would conservatively say 45mpg or better. Comfortably 200 mile range. The 4 valves and redesign accomplished this. This bike also claims 125hp @ 5500rpm and 125 fpt @ 4500rpm. The Tour may not be, but the base GW will give the ST a run for its money. My .02Most bikes these days are targeted for the 180-230 range so that's normal.. the ST, Stelvio, GS Adv are just not the norm as the added range doesn't mean much to most of the riders out there..
I will test ride both, it is an ST on steroids and with the electronic assists it could be a better handler.
