I bought my Burgman 650 used and the previous owner had the tension on the rear shocks cranked up pretty tight. Probably for a passenger. Anyway, I noticed that the Suzuki manual said that they were preset from the factory to a number "2" tension. I reset them on "2" and it allowed me to have a more firm footing and a smoother ride. Your weight would be a factor in what setting you choose I suppose. I'm 220 lbs. and it is perfect for me. I would raise the setting if I ever had a passenger. Just thought I'd pass this along in case someone else had this problem. If you're not to heavy, I guess it would be alright to take it down to a "1" setting. I'm sure most know how to reset the settings, but just in case, put your scooter up on the rear stand and grip the shocks tight with your hand and turn to the desired number. Mine turned very easy. Anyhow, you might want to try this before cutting your seat.
