• Differentiated rear tyres development based on the size to perfectly fit the requirements of each motorcycle and riding style
• 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 rear tyre
• Best performance on road use, on both wet and dry roads

DUAL Compound for sizes up to 190/50ZR-17

Structure

DIABLO ROSSO™ IV rear tyres up to 190/50ZR-17 size feature a Rayon 2-wire strand structure. According to front structure, chord stiffness has been raised by more than 30% versus DIABLO ROSSO™ III reducing the end-count and therefore more space is available for the compound to perform. Grip and wear regularity benefit from it.

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.

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.
