For what it’s worth. Top speeds are all over the place on here. I’m 200lbs my mods are Chimera intake, Takegawa cam, full Two Brothers exhaust, PCV with WB2 and 14T front sprocket. I can hold 50mph at 7000 rpms and on flat ground 55/57 at 8500rpms. Unless your putting a BBK on your bike with some other serious mods you are not going to “Easily” get 65mph cruising.
