Looking for opinions on replacement tires for my Rockster. My bike originally came with the Bridgestone 020's which I really liked for the gripiness/handling aspect. Replaced at 5500 miles due to cupping on the front tire with Pirelli Diablo Stada, replaced the set by the way. The Pirelli's never handled as well in my opinion, and now at 10,500 miles the rear is starting to look squared off in the center, similar to the cupping of the first set. I live in a city, and only ride on paved roads, although sometimes out in the country, but always paved. I am considering the Conti Road Attacks, but also wondering if the new Bridgestone 021's would be a worthy successor to the 020's? Looking to get back to great handling, but would like a set to last 5k-6k miles. Opinions and/or actual experience please.
