DIABLO ROSSO CORSA: POWER IS NOTHING WITHOUT YOUR TYRE

Pirelli Moto is delighted to announce the Diablo Rosso Corsa, the newest member of the successful ROSSO Generation and the only hypersport tyre for road and track use with WSBK technology.

This new tyre adds to the Diablo Rosso in Pirelli’s sport range and effectively replaces the acclaimed Diablo Corsa III.

Diablo Rosso Corsa matches the evolution of sports bikes’ needs in terms of handling and acceleration by transferring more horsepower to the ground than any tested reference tyre. During intense comparative tests carried out using the Diablo Rosso Corsa, the testers were able to transfer from the bike to the asphalt at least 10 Hp more from the bike to the asphalt than any other tested reference at each point of the test track, with a peak of 40 Hp. Tests were conducted using a standard production motorcycle and a standard setup, and the Diablo Rosso Corsa was found to be superior to all the other tested tyres in its ability to make the horsepower of the standard bike more usable.

The new Diablo Rosso Corsa can now also be personalised on the sidewalls for individual riders, with a set of six tyre labels that can be created online for each rider who rides on Diablo Rosso Corsa.

Horsepower

DIABLO ROSSO CORSA TURNS HORSEPOWER INTO LAP TIMES:
THE SECRET OF PIRELLI’S NEW HYPERSPORT TYRE

With the arrival of Diablo Rosso Corsa, a new way of measuring tyres and their level of performance is born: the amount of horsepower the motorcycle transfers to the ground. The latest Pirelli tyre is the first where intensive comparison tests were performed on a test circuit in order to measure the true “usable” power of a motorcycle. The results show that the Diablo Rosso Corsa at any point in the circuit, when coming up from lean and at initial acceleration, is able to transfer to the ground at least 10 more Hp than any other tested reference with a peak difference of 40 Hp. This more exploitable horsepower delivered by the Diablo Rosso Corsa translates to quicker acceleration out of the corners, higher speed on the straights and ultimately lower lap times. These tests were run using a standard production Honda CBR 1000RR with normal production suspension and standard setup as recommended by the manufacturer, including tyre pressures for normal road use.

This coveted performance has been achieved by technical features such as its III zone compound with WSBK shoulder grip and EPT (Enhanced Patch Technology), as well as its patented structural elements like its H-shaped bead and 0° steel belt with new High Performance Single Cord. Pirelli tested the new Diablo Rosso Corsa against various reference products (Diablo Corsa III, Diablo Rosso, Dunlop Qualifier RR, Michelin Power Pure, Bridgestone BT 016 and Metzeler Sportec M5) at the Siracusa test circuit.

By securing instruments commonly used to analyse the telemetry data in the World Superbike environment, Pirelli was able to accurately measure the required parameters in order to calculate the power discharged by the tyre to the ground. These parameters form true scientific logic and include acceleration (in both its lateral and longitudinal components), instantaneous velocity, and lean angle. During the various stages of the turn, the measurements were focused on the moments on corner exits and at maximum lean when the throttle is being reopened, which is precisely when a rider needs all available power on the ground to achieve maximum acceleration.

The final calculations took into account the mass of the vehicle, including both the weight of the bike and the rider. The true Force applied by the tyre to the ground is measured by the scientific formula F = m *a (force = mass times acceleration). The Power output is found by multiplying the force by the velocity (P = F * v). In this way, Pirelli’s R&D staff were able to measure the horsepower the bike was unloading to the ground moment by moment, centimetre by centimetre in various corners of the circuit in Sicily.

Testing instruments compare the real power transferred from the tyre to the ground by the new Diablo Rosso Corsa versus its closest tested competitors

Technical

PIRELLI UNLEASHES ITS NEW DIABLO ROSSO CORSA HYPERSPORT TYRE WITH WSBK SHOULDERS FOR GRIP, A PROVEN DESIGN AND PATENTED STRUCTURE

The new Diablo Rosso Corsa hypersport tyre emerges as the ideal synthesis of grip for track riding and mileage for everyday adrenaline

Pirelli Moto is delighted to announce the Diablo Rosso Corsa, the newest member of the successful ROSSO Generation and the only hypersport tyre for road and track use with WSBK technology. This new tyre supplements the Diablo Rosso in Pirelli’s sport range and replaces its acclaimed predecessor, the Diablo Corsa III, by measurably exceeding its key performance values. Diablo Rosso Corsa matches the evolution of sports bikes’ needs in terms of handling and acceleration allowing riders to reach the maximum potential of their motorcycles by transferring more horsepower to the ground.

TARGET: EVERY DAY IS RACE DAY

The Diablo Rosso Corsa’s application includes all true performance-oriented motorcycle riders who push the limits from mountain curves to the racetrack, riders who can recognize the distinction between pure racetrack and pure road usage, and those who crave the ultimate performance tyre along with an aggressive tread pattern look. The new top-of-the-range for Pirelli Moto features a broader range of sizes, EPT (Enhanced Patch Technology), and an undoubted grip level from its III zone compound.

Pirelli’s development of this ultra-performance radial tyre was aimed towards today’s modern sport bikes characterised by new technological features and electronic aids such as ABS systems, traction control, advanced electronic management systems, suspension control and gear shifting systems. Diablo Rosso Corsa is structurally adaptive to the new generation of chassis with higher rigidity, allowing for greater responsiveness for the optimum balance between grip and handling.

PRODUCT TECHNOLOGY

• Diablo Rosso Corsa is credited with 25 patents, along with grip enhancements from its Enhanced Patch Technology (EPT), a solution developed in the WSBK experiences for an optimised contact patch area at all lean angles on the road and the track, for true confidence and power transfer to the ground in any riding conditions.

• EPT is complemented by the III Zone Compound rear tyre whose new compound in the central zone guarantees long lasting performance and ample shoulder zone compound from WSBK.

• Diablo Rosso Corsa’s captivating tread pattern is designed with the winning FGD (Functional Groove Design) technology, which combines a slick-like area on the rear shoulders, while the tread grooves are selectively concentrated for an aggressive tread design that gives quick racetrack warm-up and consistent water drainage, for great control on wet surfaces.

NEW PATENTS

• “H shaped” bead – this new design optimises the sidewall stiffness, bringing increased support and precision at maximum lean angles. The layout of the “H shaped” bead wires creates uniform pressure between the tyre and rim, creating a stiffness that improves stability both at lean and also in straight-line riding, reducing the risk of tyre slippage during severe racetrack usage. A reduction of the number of steel wires used in this layout also results in lighter weight.

• High Performance Single Cord (HPSC): Using a single cord winding of the steel belt, Pirelli’s engineers were able to obtain a differentiated structure from crown to shoulder, in the centre a road-oriented winding scheme is used for street handling and a racing winding scheme is used in the shoulders for track performance, while the total number of steel strings maintains linear performance. The tread design and compounds are designed to ensure maximum safety in all riding conditions, even in the wet: confidence and safety are never compromised; in wet conditions Diablo Rosso Corsa surpasses all race replica products.

COMPOUNDS: DERIVED FROM WSBK

The front compound is the result of the top WSBK riders’ feedback, which has resulted in the development of a solution that combines the highest grip without losing tread stiffness, to guarantee the necessary support under heavy breaking and also for faster corner exit. The III zone compound on the rear represents the ideal way to offer the best performance required in different conditions (racetrack and road). The differentiated compounds between the shoulders and centre zones is the winning solution engineered to give Diablo Rosso Corsa the racing performance needed for the track as well as long lasting performance for the road:

• Long mileage is guaranteed by high mechanical resistance materials on the Central Zone with a compound derived from Diablo Rosso experience, but even sportier; Pirelli engineers have used special resins and plasticisers optimised in terms of chemical properties and quantity to ensure the best balance between dry and wet grip. A new dedicated curing process increases the compound’s wear resistance and therefore mileage.

• The wide tyre shoulders adopt a new high hysteresis compound developed and used in the WSBK arena, featuring continuous grip response and incredible traction even at high lean angles. The 100% Carbon black compound’s lower rigidity, especially at mid-low temperature, allows for very fast warm up and reduces the temperature difference on the tyre’s surface for a very linear transition from one compound to the other. Specifically tuned WSBK resins from the Diablo Supercorsa are used which function at very high temperatures and levels of stress, distinctive elements required for racetrack use. The wide shoulder zone offers WSBK grip starting from low lean angles, to exploit this new performance when needed, whether on the racetrack or on the road.

TREAD PATTERN: ATTRACTIVE DESIGN

The Diablo Rosso Corsa tread pattern adopts the same winning FGD technology (Functional Groove Design) concept of the Diablo Rosso tread, combining excellent slick-like racetrack performance together with great control on wet surfaces. The 100% slick area on the rear shoulders (nude shoulder) is available from low to high lean angles to allow WSBK racetrack feeling with calibrated grooves in the middle that maximize the contact patch: The transversal groove between the rear central section and the edges quickly disperses residual water and assures maximum grip all the way through a corner, even on very wet surfaces. Another slick area in the centre puts more rubber on the ground for traction and stability.

PRODUCT BENEFITS

Diablo Rosso Corsa retains all the outstanding features of Diablo Corsa III in terms of comfort and stability, while enhancing handling and grip to the utmost. Diablo Rosso Corsa improves duration of performance on the racetrack and above all on-road to ensure true road lasting and racetrack performance. Furthermore, Diablo Rosso Corsa improves wet performance compared to the Diablo Corsa III, confirming itself as the best in class for wet versus any race replica product.

More Power To The Ground

Motorcycle fans already know that the engine's power is never the same as the power actually used by the motorcycle, due to various other elements that dissipate energy, like the transmission.

It's for this reason, and to provide a true indication of the bike's performance, that the power available to the wheels is always measured.

Between the power available to the wheel and the power actually delivered to the ground, the important role of the tyre has to be considered. In particular, it's important to consider the tyre's ability to transfer power and to avoid slipping and sliding.

DIABLO ROSSO™ Corsa offers a new way to measure tyre performance: evaluating the ability to transfer the bike's power to the ground and expressing this as horsepower available on the ground.

In fact, Pirelli's new motorcycle tyre is the first to have undergone severe tests to measure the actual power discharged on the ground by the bike as it comes out of a turn.

The tests were carried out using one of the most popular super sports bikes in the world, the Honda CBR 1000RR. The bike was tested in its standard configuration, with normal factory suspension and set-up, and with the tyres inflated to street use pressure, as recommended by the Japanese manufacturer.

Tyre measurements were those recommended by the manufacturer: Front tyre 120/70 ZR17 M/C (58W) TL; Rear tyre 190/50 ZR17 M/C (73W) TL.

Pirelli tested the performance of the new DIABLO ROSSO™ Corsa on its experimental test course in Syracuse, which is normally used to develop high performance radial tyres. With the track's very fast, long curves, the bike's response as it exits turns can be evaluated at the precise moment of acceleration when increased power is transferred to the wheels.

The tests compared DIABLO ROSSO™ Corsa with several other tyres in the same category: Diablo Corsa III, Diablo Rosso, Dunlop Qualifier RR, Michelin Power Pure, Bridgestone BT 016 and Metzeler Sportec M5.

Thanks to the use of data acquisition equipment normally used for Superbike applications, Pirelli was able to measure the necessary parameters accurately to calculate the power transferred to the ground by the bike and therefore by the tyres.

Starting from a pure scientific standpoint, these parameters included: acceleration (both lateral and longitudinal), vehicle weight, instantaneous speed, and curve angle.

Measurements focused on the moment the bike exited the peak of the turn, when the throttle was opened; in other words, the exact moment when the rider needed the maximum power available to the ground in order to obtain maximum acceleration. In this way, Pirelli's Research & Development staff were able to measure the power in horsepower (HP) that the bike was able to discharge on the ground, instant by instant, centimetre by centimetre, throughout the various turns on the Sicilian track.

The results showed that, coming out of the turn, at the moment the bike is at maximum acceleration, DIABLO ROSSO™ Corsa is able to transfer at least an additional 10 HP to the ground in comparison to the other tyres tested.

The increased power transferred from the bike to the ground thanks to the new DIABLO ROSSO™ Corsa means faster acceleration coming out of turns, higher speeds in straight areas, and above all, faster lap times.

The new DIABLO ROSSO™ Corsa is able to offer this type of performance thanks to its innovative features including the three different compound areas on the rear area that make it possible to use WSBK solutions on the shoulder which offer excellent grip, and the Enhanced Patch Technology that increases the area of contact between the tyre and the road, making it easier to discharge the bike's power to the ground.
