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
• Lightning 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

Structure

DIABLO ROSSO™ IV raised specific Rayon cord stiffness, obtained through a larger section of more twisted strands, allowing a lower end count, adapted along the contour, differentiating stiffness lean angle by lean angle, and 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 through a larger section of more twisted strands, allowing 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 softer side 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 a lean.

Tread Pattern

As a distinctive sign for PIRELLI sporty products, the DIABLO ROSSO™ IV tread pattern is developed around the FLASH™ icon: a couple of centre grooves which provide directional stability and ensure 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 surrounding 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. The 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 the 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.
