Introducting Diabolo Rosso IV

THE SUPERSPORT TYRE FOR ROAD USE

  1. Superb grip while braking, thrust boost in extreme lean angles and brilliant traction exiting the corner
  2. Lightening handlebar response to rider inputs and smooth feedback while cornering
  3. WSBK-derived structures and contours
  4. Silica-enriched multi-compound for both front and rear tyres
  5. Best performance on road use, on both wet and dry roads

Within motorcycles scenario, high-displacement (> 999 cc) bikes set 200hp as a standard threshold, often reaching the astonishing power of more than 215hp for several Superbike and Hypernaked machines. In this picture, we must include also sporty crossovers capable of delivering 160hp on 240kg machine more than 140 cm tall and 600cc Supersport and Naked bikes with almost the same weight of the bigger displacement counterpart but with no more than a half of the power.
DIABLO ROSSO™ IV sets a reference in the Supersport segment for all these classes of motorcycles. Therefore PIRELLI decided to differentiate the rear tyres product characteristics based on the size, and therefore the type of motorcycle in order to perfectly deliver the requirements for each rider.

INFORMATION & SPECIFICATIONS

THE SUPERSPORT FRONT TYRE FOR ROAD USE
  • The front tyre matches perfectly with each rear tyre, showing an outstanding versatility to very diverse riding conditions.
  • Superb grip while braking, thrust boost in extreme lean angles and brilliant traction exiting the corner
  • Lightening handlebar response to rider inputs and smooth feedback while cornering
  • WSBK-derived structures and contours
  • Silica-enriched multi-compound front tyre
  • Best performance on road use, on both wet and dry roads
  • Full Silica DUAL Compound
Structure

DIABLO ROSSO™ IV raised specific Rayon cord stiffness, obtained thought larger section of more twisted strands allows a lower end-count, adapted along the contour, differentiating stiffness lean angle by lean angle, supporting the dynamic needs for an outstanding riding experience. These characteristics deliver to the rider a great contact feeling alongside a solid stability sensation.

Contour

DIABLO ROSSO™ IV raised specific Rayon cord stiffness, obtained thought larger section of more twisted strands allows a lower end-count, adapted along the contour, differentiating stiffness lean angle by lean angle, supporting the dynamic needs for an outstanding riding experience. These characteristics deliver to the rider a great contact feeling alongside a solid stability sensation.

Compounds

A dual compound front tyre is coupled with Cap&Base rears: a dual compound for low to medium displacement motorcycles up to 190/50ZR-17 and a tri-compound for Superbike and Hypernaked machines sizes 190/55ZR-17 to 200/55ZR-17.

The hard layer due to the high content of Silica and the low Tg delivers outstanding grip in cold and wet conditions. The side softer layer (accessed when in lean angles over 35°) offers excellent grip and delivers a brilliant contact feeling. Combined this gives the rider the option to adjust the trajectory while cornering or to delay braking ahead of entering into lean.

Tread Pattern

As a distinctive sign for PIRELLI sporty products, DIABLO ROSSO™ IV tread pattern is developed around the FLASH™ icon: a couple of centre grooves which provide directional stability and ensures wear stability. FLASH™ is also accountable for water draining from the centre to outside the contact patch when upright. FLASH™ tails of varied length are distributed surround the centre design, outlining mid-lean grooves. Tails are a constitutive element of the tyre behaviour, providing the right tyre flexibility and efficient water evacuation and an absolute wear uniformity. Tread Pattern design of DIABLO ROSSO™ IV with slicker mid-lean areas evolves the DIABLO ROSSO™ III one, giving support at lean angles where water drainage is useless, which means over 35°. It is characterised by a large slick area on shoulders, which results in excellent grip and line holding while cornering at extreme lean angles. Besides the family feeling, tread pattern layout plays a relevant role in DIABLO ROSSO™ IV performance.
