Race and Stunt
I have a 2017 Zx10r full bolt on... flash filter exhaust. I last season ran a -1 front sprocket but the front end will not stay down.. so I went back to stock. The OEM sprocket is back on it.
I just roll raced a 2010 s1000 from a dead stop to a 30 then full throttle, and he put buses on me.
