What have you ran on this bike? And 16, 53!! With a 190/50 tire, which I assume the hook up is, the top speed would be 147.8 at 14k. That seems a little big and you would be close to if not hitting rev limiter when crossing line or before and is not great on street at all (if even ridden on street). I am 16/47 and run 1.4 60 fts and am only on top of 5th. I am not bashing it, I just want to know if you got results or if it was too large.
