The Pirelli DIABLO ROSSO IV R 240/45R17 82W is a motorcycle tyre engineered for spirited road riding and aggressive sport use. It is intended for riders who demand strong grip in fast cornering and firm braking on twisty roads and mixed surfaces. The tyre emphasises dynamic handling and rapid warm-up characteristics so it performs from the first miles of a spirited ride. Cornering stability and braking distance optimisation were key targets during development to enhance rider confidence in sport situations.

The tread pattern features asymmetric blocks and siping that manage heat and promote efficient water evacuation for improved wet grip during sudden showers. A high-grip compound and focused contact patch design increase adhesion when leaned over, while the construction supports consistent wear across the useful life of the tyre. Steering response is precise and progressive, allowing accurate line selection and stable transitions between inclinations. Rolling resistance is managed to keep reasonable mileage without undermining performance characteristics.

Riders gain immediate feedback and predictable behaviour when pushing into corners, with shorter stopping distances under load. The DIABLO ROSSO IV R suits sportbikes where handling precision and maintained traction are essential for confident, enjoyable riding.
