The latest in Pirelli technology has landed in Australia, the Diablo Rosso IV tyres.The tread pattern design of the Diablo Rosso IV features slicker mid-lean areas. This is an evolution of the Diablo Rosso III, giving support at lean angles where water drainage is useless (over 35°). This means a large slick area on the shoulders, which results in excellent grip and line holding while cornering at extreme lean angles. 

The Diablo Rosso IV tread pattern is developed around the Flash icon which is synonymous with all Pirelli sport tyres. Flash features two prominent centre grooves providing directional stability and ensuring wear stability. They also provide water drainage from the centre out for the contact patch when upright. Flash tails of varying lengths are distributed around the centre design, outlining the mid-lean grooves. These tails are an important element for the tyre’s behaviour, providing the right tyre flexibility, efficient water evacuation and wear uniformity.

The Rosso IV boasts a Silica-enriched, multi-compound in both the front and rear tyres, combined with WSBK-derived structures and contours. Pirelli has spared no expense in development, this is demonstrated in the confidence that the Rosso IV inspires. It offers superb grip under braking, thrust boost in extreme lean angles and brilliant traction when powering out of corners.

The hard layer on the front tyre 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. The new Diablo Rosso IV’ has increased the Rayon cord stiffness, obtained through a larger section of more twisted strands, adapted along the contour, which differentiates stiffness depending on the lean angle. Combined this gives the rider the option to adjust the trajectory while cornering or to delay braking ahead of entering into lean.

The dual-compound rear up to 195/50 r17 features a Rayon 2-wire strand structure. The chord stiffness has been raised by more than 30 per cent over the Diablo Rosso III, reducing the end-count freeing up the space available for the compound to perform. The full silica dual compound rear offers a quick warm-up and a significant grip level irrespective of lean angle, even in wet conditions. In relation to the dimension of the tyre, and therefore of the contact patch, a dual compound with more continuity ensures the best stress distribution and wear uniformity.

This endurance-racing compound features a 5-zone layout, which trades wet grip on high lean angles for thrust boost to cope with the extreme cornering speed and the astonishing engine outputs of modern performance motorcycles. It features a 3-wire strand Lyocell structure which translates to a deformation ratio considerably lower than usual street tyres. The soft full silica mid-rubber strip ensures performance, whilst delivering a safe sporty ride across all weather conditions.
