Pirelli Diablo Rosso IV 190/50 ZR17 Rear Motorcycle Tire - Partnumber: 3979700
Dominate the street with the fourth generation of Pirelli's iconic Diablo Rosso family. Developed using racetrack profiles derived directly from the FIM World Superbike Championship (WSBK), the Pirelli Diablo Rosso IV 190/50-17 is customized specifically for modern high-horsepower naked machinery and supersport motorcycles.
In this specific 190/50 ZR17 footprint, Pirelli implements a specialized high-stiffness structural configuration combined with an optimized dual-compound layout to provide predictable handling feedback, short braking distances, and consistent cornering lines under heavy loads.
-
Bespoke 190/50 Structural Engineering: Unlike larger sizes that use Lyocell chords, the 190/50 dimensions utilize an advanced Rayon 2-wire strand carcass layout. This design raises chord structural stiffness by over 30% compared to the older Rosso III, reducing the structural wire count to give the tread compounds more physical space to flex and grip.
-
Cap & Base Dual-Compound Layout: Tailored with a smart multi-compound architecture. The center section uses a harder, silica-reinforced base compound that runs cooler on highways for premium straight-line longevity, while the outer shoulders consist of softer full-silica matrices for quick thermal warm-ups and exceptional dry cornering traction.
-
Evolutionary "Flash" Tread Design: Features Pirelli's iconic lightning-bolt water evacuation channels. The spacing layout reduces the void-to-rubber ratio along the mid-lean zone, adding physical block solidity for sharper lateral thrust while smoothly handling sudden rain on wet tarmac.
-
WSBK Multi-Radius Profile: Sharp, race-derived contours deliver immediate lean transitions and effortless, neutral steering input. A flatter profile along the absolute edge of the shoulder expands the active rubber contact area for unshakeable tracking mid-corner.
