The Pirelli Diablo Rosso IV is a performance summer motorcycle tyre with owner and test support for wet grip, precise feedback and quick turn-in. Its dry lap pace was less competitive in a sport and hypersport comparison, while long-term wear remains less firmly established.
The Pirelli Diablo Rosso IV has broad agreement between its small owner sample and single independent test on wet-road confidence and feedback. All eight owner reviews are favourable, with wet grip the most consistent strength and dry grip also well supported. In the 2025 PS Sport and Hypersport Motorcycle Tyre Test it finished fifth of twelve overall and fifth in wet handling. The testers praised precise feedback, a short warm-up phase and controllable slides when ridden harder.
The qualification is outright dry lap pace: it was eighth of twelve, 2.8% slower than best, in that mixed sport and hypersport field. This is a relative limitation rather than a contradiction of the favourable dry-grip accounts. The evidence fits everyday sporty riding more clearly than a claim to leading track speed. Most owners reviewed it at mid-life or end-of-life, but several accounts cover the front only and the small sample leaves tread life and worn performance uncertain. Isolated reservations about cold stability and worn grip do not yet form a repeated pattern.

Built from every independent test result and vetted owner review we hold for this tyre - the evidence is all further down the page. Data updated August 2026.
The Pirelli Diablo Rosso IV is a sport tyre that shares many characteristics with its hypersport sibling but is more oriented toward everyday sporty usage. The extremely transparent feedback—described as allowing you to "feel everything precisely"—and short warm-up phase make the Rosso IV tremendously enjoyable to ride. Like the Metzeler M9 RR, hard pushing creates some movement in the rear, but the resulting slides remain well-controllable. It demonstrated impressive wet handling capabilities, ranking fifth overall in wet lap times among all tyres tested, making it one of the better wet-weather performers while still maintaining strong dry-track capabilities.

Questions and Answers for the Pirelli Diablo Rosso IV
Sorry, we don't currently have any questions and answers for the Pirelli Diablo Rosso IV. Why not submit a question to our tyre experts using the form below!
The Pirelli Diablo Rosso IV receives favourable scores from all eight owners, with wet grip the clearest shared strength. Dry grip also draws substantially more praise than criticism, and several riders describe quick turn-in and useful feedback. Braking receives some support, though from fewer reports than grip. Most reviews are from mid-life or end-of-life use, but the small sample and several front-only accounts limit any broad conclusion about tread life or how performance changes as a complete set wears. Individual reservations about worn grip and cold-weather stability have not emerged as repeated complaints.

The Maxxis came stock, and I didn't have major issues with them, but the level of confidence and consistency in cornering and grip is better with the Pirelli. I would say especially in wet conditions. My bike, due to its balance and weight (KTM Duke 890 R), doesn't really challenge the tires, I would say. I would love to try them on the track..
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.

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.
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.
