I have the same scoot. Stage 1 with V&H. Had her at 118 MPH a year ago and I think there may have been a bit more. She was wound up pretty tight, but the engine had no sign of killing itself. Maintained the speed for maybe 3 seconds.
Y2KFLHRCI I would not worry too much about 5th Gear Redline. A 85 -90 MPH cruise is what she was built for. Kick back and enjoy her bro.
