The Pirelli Diablo Rosso IV Front & Rear Motorcycle Tires set the benchmark for hypersport performance, trusted by Factory SuperBike, WorldSBK, and riders worldwide for their razor-sharp handling and grip. Engineered as street-legal sport tires, they feature a dual-compound front and bi-/tri-compound rear with 100% silica center for 30% better wet grip than Rosso III, per pirelli.com. WSBK-derived FLASH tread and multi-radius profiles ensure agile turn-in and stability on road (33 psi front/36 psi rear, cold) or track (30 psi front/30 psi rear, warm), ideal for Yamaha MT-09, Ducati Monster, and more.
