I took delivery of my Silver '05 Burgman 650 today; what a high. The dealer, as others have reported, had no idea about the OD. He said he will check with the rep and get back to me; I won't hold my breath. I didn't have much of a chance to ride it today, but I will report on it as things progress. Right now let me just say it's more bike to handle than the 400, but I don't think that will be a problem. More and pics to follow.
