When most people think about tires, they think about the rubber that sits underneath their car or motorcycle.
They might not give a lot of thought to the different types of tires available on the market, but there are a lot of options out there for both cars and motorcycles.
What are differences in design, traction, tread life, price, maintenance that make it ideal for particular vehicle or motorcycle?
• Ideal for riders who want performance upgrades for their motorcycles
• Higher grip, enhanced “fast” handling and performance consistency
• Bi-compound scheme both on front and rear tire
• Slicker tread pattern compared to DIABLO ROSSO IV
• Racing-derived technologies applied to profiles and structures
ROME, Ga. (February 10, 2021) – Pirelli presents the new DIABLO ROSSO IV Corsa, the high-performance hypersport tire that raises the bar of sport riding even higher within the DIABLO ROSSO family. The new DIABLO ROSSO IV Corsa represents a fiercer version of the DIABLO ROSSO IV super sport tire, created to satisfy the most demanding motorcyclists seeking a tire capable of high performance, to fully utilize the potential of their bikes.
DIABLO ROSSO IV Corsa was born in the year in which Pirelli celebrates its 150th anniversary and becomes an integral part of the celebrations. During 2022 a limited edition DIABLO ROSSO IV Corsa pays homage to this milestone and features the Pirelli’s 150th anniversary logo on its sidewall.
Formed in Milan on January 28, 1872, the company began its business with diversified rubber products, making the first tire for bicycles in 1890. Always passionate about competition, Pirelli participated in the first motorcycle races in 1897 and today continues with the role of sole supplier to the Superbike World Championship, a collaboration that started in 2004, as well as being the most successful brand in MXGP. Today Pirelli is the only tire company focused exclusively on the consumer world, with products and services for cars, motorcycles and bicycles.
Who is DIABLO ROSSO IV Corsa designed for?
DIABLO ROSSO IV Corsa is the ideal choice for:
• Motorcyclists who love a dynamic riding style on winding roads and mountain passes, who want a tire to match the sporty performance of their motorcycle.
• Motorcyclists who are passionate about tuning, who look for performance upgrades and take care of the bike set-up and aesthetics. These riders seek the optimal set-up of their motorcycle according to the type of use, also through the upgrade to high-performance equipment. They also recognize the lightning-shaped tread design, here interrupted, as the iconic symbol representing DIABLO ROSSO sporty performance.
The benefits of DIABLO ROSSO IV Corsa:
The main benefits of DIABLO ROSSO IV Corsa are:
Higher grip in dry conditions thanks to a slicker tread design that guarantees a larger footprint area alongside the use of innovative compounds that increase mechanical grip levels.
Enhanced high-performance handling and precise feedback. The innovative technologies applied to the carcass make DIABLO ROSSO IV Corsa able to adhere to the micro-roughness of the asphalt, ensuring precise feedback and a feeling of control.
Performance consistency over multiple riding sessions, made possible by the characteristics of the tread pattern, where the intended repetition of the grooves offers high resistance to stress, and, by the new arrangement of the compounds, ensures optimal thermal balance.
THE TIRE IN DETAILS
Tread Pattern
The tread design of DIABLO ROSSO IV Corsa features a calculated repetition of the central grooves and a slicker shoulder area, for a void/fill ratio 25%[1] lower than DIABLO ROSSO IV.
In the central area, the group of longitudinal grooves assures directional stability and water evacuation. Their orientation follows the wear waves and enables an even wear, while their position increase the structural stability of the tire to give performance consistency over multiple riding sessions.
In the intermediate area, linear grooves of different lengths are positioned using a scheme that balances compound flexibility and water evacuation. DIABLO ROSSO IV Corsa features a large slick area on the shoulders, able to offer high levels of grip, precision and stability at maximum lean angles.
Compounds
The front tire is divided into three areas using two different compounds:
The central band has a Full Silica compound that occupies around 45% of the section width and is present in the contact area used up to 25 degrees of lean angle.
The side areas have a softer compound, also Full Silica, thanks to the use of innovative resins that offer excellent grip and improve the front tire feedback.
The rear tire also has a bi-compound scheme for excellent road performance and works in harmony with the front.
The central Full Silica compound allows for a quick warm-up and excellent chemical grip on different surface conditions.
The shoulder compound is 100% Carbon Black and derives directly from the compounds of DIABLO Supercorsa SC used in racing competitions. This compound is able to offer support at full lean and traction during acceleration managing the torque generated by the latest generation superbikes.
Profiles
Pirelli exploits all the know-how acquired in the fastest production-derived motorcycle championship. The profiles of DIABLO ROSSO IV Corsa are therefore race-derived and are characterized by a multi radius design that improves the tire’s handling.
The central area has a sharper profile to facilitate immediate lean and rapid change of direction. In the lateral areas, on the other hand, the profile curvature is less accentuated in order to increase the contact area and ensure maximum traction when cornering. Front and rear tires follow a similar profile design, thus ensuring a perfectly balanced and neutral behavior of the set.
Structure
With DIABLO ROSSO IV Corsa Pirelli uses a racing-derived structure with zero-degree steel belt, which manages to adapt perfectly to different levels of stress without compromising comfort and work optimally with the most advanced electronic control systems.
The stiff cord technology features structural cords that are more rigid and at the same time distributed with less density (-20%) compared to a standard sport tire[2]. This scheme leaves more room for the rubber compound, which improves riding feeling and precision thanks to its damping properties, thus transmitting to the rider, a safety feeling and control of the motorcycle.

The DIABLO ROSSO IV Corsa range includes the following sizes.

The Latest Evolution of the Multistrada Family will be on Sale Equipped with SCORPION™ Trail II as Original Equipment Tires, While Also Being Homologated for SCORPION™ Rally STR and SCORPION™ Rally Off-Road Use
MILAN, Italy (November 30, 2020) – The new Ducati Multistrada V4, recently presented to the public on the digital platforms of the company from Borgo Panigale, represents the fourth generation of Multistrada and is an important step forward in its offering for the maxi enduro segment. The Multistrada V4 is an even more high performing motorcycle compared to its predecessor; designed to show a sporty attitude and versatility at the same time, capable of tackling all conditions in complete safety, on- and off-road.
Pirelli has worked closely with Ducati since the inception of the Multistrada project in 2003 offering to the company from Borgo Panigale tires focused on supporting the attributes of this machine in terms of performance and safety. The first version of the Ducati Multistrada in 2003 was equipped with Pirelli SCORPION™ Sync, the new 2010 model adopting Pirelli SCORPION™ Trail, while the Multistrada 1200 in 2012 was the first to have as original equipment the revolutionary Pirelli SCORPION™ Trail II tires. With the recent introduction of the fourth generation Multistrada, the partnership between this motorcycle family and SCORPION™ Trail II is increasingly strengthened, and it is joined this time by the motorcycle additional homologations for SCORPION™ Rally STR and SCORPION™ Rally tires.
