This tire is engineered to provide excellent grip, precise handling, and consistent performance, whether you're riding on the street or pushing your limits on the track. Its key features and benefits include:

• Multi-Compound Design: The Diablo Rosso IV utilizes a multi-compound design, featuring different rubber compounds in the center and shoulder areas of the tire.
