Pirelli’s Diablo Rosso IV Corsa tyres are designed for spirited road riding and fast trackdays. I’ve been using them on my 2014 Suzuki GSX-R750 for eight months and over 2200 miles for backroad blasts and road trips to Le Touquet and Spa-Francorchamps to spend a day lapping the magnificent Belgian circuit. In this long-term test video, I’ll let you know how they compare to other sports tyres and how well they’ve lasted.
