I kept my stock gearing!! But converted to 520...if that does anything lol. And I have turbo joes super hyphy ecu flash as well as a power commander that was dynoed
Bone stock I've seen 145 "naked" and 152 with my Givi winscreen on and tucked. It will go faster though... Ps. mine will indicate 75 mph bouncing the rev limiter in first. Not how i normally ride, just did it for the hell of it. lol
