The LC4 motor is counterbalanced which reduces vibration quite a bit however; the motor does vibrate quite alot if you are doing highway stints. I can live with the vibration and it becomes no problem for me during all day long hauls. Once properly broken in this motor pulls pretty hard, keep in mind it is a 620cc single cylinder. If you are unsure about buying one, the dealer should offer a test ride. You test drive a car before you buy, right?
