As far as handling goes, the best handling bike that I ever owned was a 1973 Norton Interstate. When I picked up the Norton at the dealer in London, both tires were 4.10 x 19" Dunlop. At some point when the Dunlop tires wore out I purchased Pirelli tires and they improved handling.
Later on when the tires needed to be replaced I used Pirelli tires again, but I went with a more narrow tire on the front and a 4.10 on the rear. Handling noticeably declined.
The next tire change I used Pirelli size 4.10 on both the front and rear and the handling was absolutely great.
One other observation about the Norton, both front and rear tires wore out at the same time. I rode the Norton for over 30 years so it was easy to know what worked and what did not work. Most riding was done on two lane asphalt roads with a speed limit of 50 to 60 MPH.
