I ride a 2004 CBR600RR and use the Bridgestone bt 016. I love this tyre coz of the grip on the edges and the many kms in the middle. My riding is sports/touring with more emphasis on the sports riding. I put the front and rear tyre on the bike at the same time but I noticed that the front tyre is worn out (mostly on the edges) while the rear tyre still has many kms left on it. From what i know that's strange, usually the rear gets worn out much faster than the front. I used the Pirelli Diablo before and that was the case. Is it the tyre compound? Do you recommend a similar tyre that could be better than the bt 016?
