Now on to its fourth generation, completely revised from the ground up, the Pirelli Diablo Supercorsa SPV4 Tires are as close as you can get to a race tire that is still street legal. Using compounds and structure directly pulled from the tires used in the FIM Superbike World Championship. Pirelli's motto is in full display here "we sell what we race, we race what we sell" and when you lean into that race spec compound on the shoulder of the tires you'll feel it. Perfectly at home carving your way through a mountain pass or knee down at the track, the Supercorsa SP V4 tires will make you the only thing holding your bike back.
