I need to replace front tire in my S2R1000. When I bought my Monster in August, the previous owner just replaced the rear tire so I don’t need to get one now. Currently I have Bridgestone Battlax (front and rear) and I was thinking about upgrading to Pirelli Diablo Roso up front. Since those tires have different geometry, lean angles and handing characteristics is mixing acceptable (Pirelli up front and Bridgestone on rear) or should it always be done as matching pairs? Should I just get another Battlax for front? I don’t do race track just street riding. Thanks.
