100 and fifty years—that’s how lengthy the corporate we now know as one among Italy’s premier tire producers has been in existence. When Giovanni Pirelli based his restricted partnership again in 1872 to provide “elastic rubber objects,” there weren’t even any true manufacturing bikes obtainable to the general public but; Indian didn’t begin turning out bikes till 1902, and Harley launched its first manufacturing mannequin in 1905. To its credit score, the famed Italian model hasn’t rested on its laurels, as evidenced by final 12 months’s Diablo Rosso IV Corsa revamp. For its most up-to-date replace, Pirelli has launched the fourth era of Diablo Supercorsa rubber, which is now obtainable to the general public in two variations: the SP possibility, designed primarily for avenue use, and the SC model, obtainable in varied compounds for the observe.
Pirelli’s first-generation Diablo Supercorsa SC grooved racing tires didn’t come into the scene till 2007, however the Supercorsa SCs went on to develop into the benchmark for the Supersport and Superstock classes, and Pirelli was awarded sole tire provider standing to the World Superbike Championship even sooner than that. Within the client world, the Diablo Supercorsa SP has been chosen as OEM tools on a few of the most fascinating supersport and hyper-naked fashions at the moment obtainable (taking a look at you, Ducati Panigale V4 and V4 S). With successive generations of Diablo Supercorsas persevering with to push the technological envelope, the entire sequence grew to become a hit story, not simply from a design standpoint, but in addition by way of gross sales quantity; since their debut greater than 3.5 million Diablo Supercorsa tires have been offered worldwide.

Pirelli says each variations of the Diablo Supercorsa V4 tires (”V4″ signifies the fourth era) are totally new in contrast with the earlier Supercorsa V3s, by way of tread sample, compounds, and profiles, and far of their improvement has been influenced by the model’s involvement within the World Superbike Championship sequence.
On the competitors facet, the treaded Supercorsa SC V4 (“SC” is for “Particular Compound”) targets skilled and semi-professional riders, in addition to trackday fanatics or riders who need further efficiency with out making large adjustments to their bike’s settings. The Supercorsa SC V4 improves on the Supercorsa V3 by providing the latest-generation compounds for higher grip, in addition to an improved construction with wider part structural cords for stability when exiting corners; it shares its construction and supplies with Pirelli’s Diablo Superbike tires and is designed to be used with particular tire pressures used on the observe. The multi-radius tire profile, developed with classes realized within the WSB sequence, is likewise tweaked to boost rideability and stability at excessive speeds, whereas the slick shoulder space gives better grip in corners. The entrance profile goals to enhance dealing with by attractive riders to lean into corners earlier for faster directional adjustments, with the rear following the identical sample and comparable geometry to make sure synchronized efficiency. Pirelli additionally up to date the tread sample with what it calls “Flash evolution,” for smoother suggestions at lean and higher consistency.
The Supercorsa SC V4 is accessible in three compounds for each the entrance and rear.
SC1 – Entrance: delivers most really feel / Rear: provides efficiency at excessive temperatures with not very abrasive asphalt
SC2 – Entrance: provides most stability and consistency / Rear: good for constant efficiency; best for low temperatures or extraordinarily abrasive asphalt
SC3: Best option for prolonged observe periods, however not meant for skilled racing
The Diablo Supercorsa SP V4, alternatively, caters extra to spirited avenue riders (“SP” stands for “Sport Manufacturing”), however as you would possibly anticipate, is designed to fulfill the mandated restrictions discovered on street-legal bikes—such because the velocity index requirement (W). The SP tire can be much less delicate to temperature, and made to warmth up extra rapidly whereas additionally providing extra mileage because of its use of various compounds. Pirelli says it’s aiming the SP model at riders hooked on strafing apexes each on the observe in addition to within the canyons, which incorporates trackday rats seeking to trip to the circuit after which flip laps with out having to swap tires.
To attain these pretty disparate objectives, the Supercorsa SP V4 depends on twin compounds and the newest construction on each the entrance and the rear tire for optimum grip at lean and a greater contact out of turns. Pirelli additionally says the tire is designed to supply longer-lasting mileage, although its profile and tread sample is equivalent to that of the SC model, with the brand new “flash” sample on the heart damaged up with a slick space for better contact between rubber and street floor. What units the Diablo Supercorsa SP V4 other than Pirelli’s different hyper-sport-focused hoops, although, is its efficiency underneath varied tire strain eventualities. Pirelli says the tire bead is designed to offer most efficiency whether or not utilizing increased on-road pressures or the decreased pressures wanted for observe periods.
The Supercorsa SP V4 makes use of a twin compound association each on the entrance and the rear. The entrance’s structure contains a central and base compound paired with a second compound on the tire shoulders; the bottom compound, made totally of silica, covers all the profile of the tire and contacts the asphalt on the central part. The shoulder compound is similar as on the SC3 racing model, and makes use of 100% carbon black formulation.
The SP V4 rear tire brings a softer central compound (100% carbon black) and a wider facet, however retains the identical base compound because the entrance, which Pirelli says is optimized to work in a broad vary of temperatures. The compound on the tire shoulders is similar as is used up entrance (the SC3), for max grip on high-speed exits. The bottom compound, which is beneath the 2 compounds contacting the asphalt, is a 100% carbon black formulation.
With the discharge of the Diablo Supercorsa V4, Pirelli says it’s now completed its revamp of the fourth era of the Diablo sport household which started in 2021 with Diablo Rosso IV. The 2023 Pirelli vary now consists of the Diablo Supercorsa SC V4 observe tire, the street-focused Diablo Supercorsa SP V4, the Diablo Rosso IV Corsa, and Diablo Rosso IV, with every tire set lined by patents developed by Pirelli within the World Superbike Championship. The distinction between them lies in the kind of use, desired efficiency on dry and moist asphalt, and within the mileage every one provides.
