Not one negative motorcycle chain issue on the stuff. It's the same with the guys needing supersport tires for the street like they are benefiting from them. A few are fast, but most are not, and more than most are wannabe racers that just want the latest and coolest. I use to think that way until...guess what....I TRIED different tires (Dunlop Roadsmarts). I've experienced it performing like a bat out of hell and begging for more stress. Never gives up and keeps performing well. God bless the shit!
