Hey John, You´ll love your new scooter....but yeah, it will vibrate, most notable at 65-75 mph. Get yourself a crash bar (old school term for ´safety bars´) and mount a couple of rubber foot pegs. They´ll absorb a lot of the vibration on the longer rides. In the old days I rode the old 1974,74 model....It was hard to hang on to the grips. My 99 Heritage Softail Classic is an awesome ride...but if I was worried about ´smoothness´ I´d drive my wife´s caddy. Good luck, broPaul.
