Pirelli Diablo Rosso IV

Tyres are overall great when fresh fast heating even wet grip is great but as they get used they tend to lose grip and only grips great when fully heated but if it cools down a bit it slowly loses grip again at the end i got a lot of tyre spin while accelerating straight or out of corners even reduced my lean angles because couldnt trust it. Mileage not bad about 10k kms front still had little to the marker. Had a few track days havent let me down once great feedback you can brake hard even on the sides it won't slide. Had a few rear spins while accelerating out of corner on track but that might not be the tyres fault :) however the tyre heats up to crazy termperatures on track but never had problems with it and its not a track tyre so its fine. Great tyre would buy them again but it should stay consistent till the markers after that i can accept it loses grip, or maybe the track days eat it up.

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.

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.

An excellent hyper sport tire for the road.

I rode this tire for over 4000 miles and it proved more than great. All the rave reviews are well deserved.

I can compare it to Bridgestone Battlax S22s and they offer most of the same experience while lasting longer.
Very quick to lean over, surprisingly stable when upright and at slow speed, you can literally let the bike balance itself at slow speed, which is a rare trait in hypersport tires.

Braking distance is very good.

For the wet grip, I can't say I rode it too much in the wet, but behaved quite well when I did.

On one occasion, I was riding on the highway, at night, early spring, with air temperature below 5 degrees and rain sipping, I noticed that above reasonable speeds, so north of 120 km/h, it starts to lose directional control, but as soon as the speed dropped to around 110, it all settled. I tried to replicate it one or twice more in that journey and every time, the behavior was consistent.

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 tyres 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 tyre 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 tyres. 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.

Changed from Bridgestone in the kawasaki, to Pirelli Diablo Rosso iii in a Ducati Supersport. Happy with the change.The tyre 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

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.
