190/55 ZR 17 DIABLO 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.

THE SPORTIEST TYRE FOR ROAD USE, REGARDLESS OF THE WEATHER CONDITIONS
A dual compound front tyre is coupled with Cap&Base layout rears: a dual compound for low to medium displacement motorcycles and a tri-compound for Superbike and Hypernaked machines.
Front tyre
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.
Dual compound rear tyres, up to 190/50 ZR 17
The full silica dual compound rear offers quick warm up, significant grip level regardless of lean angle (also in wet conditions) and riding smoothness. In relation with the dimension of the tyre, and therefore of the contact patch, a dual compound with less compound discontinuity ensures the best stress distribution and therefore delivers riding feeling and wear uniformity.
Tri-compound rear tyres, from 190/55 ZR 17 above
Introducing an endurance-racing compound, the 5-zone layout moves the trade-off on high lean angles from wet grip to thrust boost to cope with the extreme cornering speed and the astonishing engine outputs of modern performance motorcycles. The soft full silica mid rubber strip ensures performance whilst delivering a safe sporty ride – across all weather conditions.
