I merged your post with this radial tire thread. 15 pages talking about tires.Before anyone yells at me, I did search the forum for a tire discussion and didn't find what I was looking for. I am replacing the tires on my 2016 V7 II Racer. My #1 criteria is good/consistent grip in colder weather.
Best tire out there to date Conti Road Attack 3s, 110/80-18ZR, 130/80-17R (150/60-17 for the V7-850 only). Questions from there are all well covered above.
