Writing about the
Pirelli Diablo Rosso IV given

Driving on
mostly motorways for 800
spirited miles
I ride 4 motorcycles that use 120/70's and 190/55's. I spend most of my time on very curvy and hilly roads and ride them aggressively. When I change out my tires my chicken strips are into the "Diablo" embossing at 40 psi F /40 psi R. I had Rosso Corsa II's on all 4 bikes and have now started using Rosso IV's. In the dry with the same tire pressures the Rosso IV's have exhibited the same characteristics as my Corsa II's. I have gone to my mental lean limit (as my Corsa II's) without any change in feel or confidence. In the wet, my Rosso IV's have behaved noticably better. However this may be more of a confidence issue rather than a performance issue because I know the sipes (water courses) go much wider on these tires. I did occassionally slip on my Corsa II's but haven't yet on my Rosso IV's. There was a huge performance difference when I changed from Rosso II's to Rosso Corsa's. There was a difference (better) when I went from Rosso Corsa's to Rosso Corsa II's. I have not felt any performance difference, other than riding in the wet, going from the Rosso Corsa II's to the Rosso IV's. I am anxious to see if there will be any difference in the mileage I was getting before on my Rosso Corsa II's.
