I gotta tell ya. I switched from the Pirelli Sport Demon to the Michelin Pilot Activ tyres. I put a 150/70 on the rear, and stock size 100/90 on the front of my Thruxton. These Pilot Activ tyres are good, the bike sticks well in the corners, and doesn't get all squirrelly on the tar snakes, as the Pirellis did.
