No, why would I need to ride one for goodness sakes? It's the same bike as I've got right now, but with a fraction more power.
In the higher gears you will be feeling the torque as you pass slower through the rev range.
We already know for a fact it's slower from 0-60 mph than the 'old' R1200. After that I know for a fact it's no quicker up to 100 mph.
So how fast do you want to be going to prove it's a fraction faster than the old one? It doesn't matter in the real world, for 90% of the riders on here.
If it's faster from 100 to 130 mph, who the fuck cares? It's optimal operating range is 0-80 mph anyways.
The ONLY benefit will be more torque for heavy riders, or carrying pillion or luggage.
In my opinion.
