2003 GSXR 600 - Was on Metz Z8s for running back and forward to work in winter conditions, have used Michelins, Bridgestone T30s and other sporty Pirellis, now better weather on the way, i hope, put these on and bike feels brand new again. Day one in wet was surprisingly good. Comfier than tired Z8s. Turn in wet and dry is great. Can brake hard on its side again. Hopefully rear hard centre will last well as these are not cheap but do perform well.

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.

Front-only review. I switched from DR3 front to DRIV four on the front, DR3 on the rear still had life left. They go well together, will replace the rear next month. I thought the DR3 was the finest tire I had ever ridden in my 3 decades of riding, and the 4 is noticeably better! sticks like glue, even when brand new. Warms up quick. Solid in rain, better than my 3. Extremely predictable as I push my lean angle limit -- on this tire, farther than I've done in my career. And it's all due to the tire 'wanting more lean' all the time! very predictable and super grippy, smooth progression-- seems to suit the Tuono's handling needs really well. I've had issues on Michelins and especially Metzelers, where the front will tell you when to stop your lean -- the 4 just keeps saying "give me more!" It almost seems to grip better, the farther over I go. Remarkable.

Front only review on a PCX 125. Previously I was a bit disappointed on using DR2 as they're easily cupped in 3 months. Switching to DR4 gave much better responses. Grip on dry and wet roads are definitely better, warms up quickly, very confident to lean with. After two years and 10K miles it didn't show any signs of cupping at all, unlike the previous DR2 I've use. Great to buy again next time.

Changed from Bridgestone in the kawasaki, to Pirelli Diablo Rosso iii in a Ducati Supersport. Happy with the change.The tire is better in precision and lean angle. Now after 2 sets of PDRIII, I tried PDRIV. Feedback, Warming Time and lean are even better. whats not better...Price(+20%)and Wear. Buy again for sure
