I have used several different brands of tires on my motorcycles but so far I like the Pirelli Diablo Rosso 2 tires the best. Great all weather traction and handling. Price is good. Have been through about 5 rear tires now and three front. Will definitely continue to use these on my ZX10R and will be putting them on my 650R when It needs tires next.
Tried Michelin pilots, kumhos, shenkos, Dunlop and Pirelli is by far the best, completely different ride smooth grip around corners, nice when stopping and no slip out while accelerating.
