Jack, I for one am not scared of the maintenance of a 650. Out of the 10,000's of them out there the failure rate is small. If I were looking for a new one I would try for a low mile 2007 and up. But if the price was low enough I would pick up a low mile 2003 or 2004 and do the Polish adapter mod and ride smiling the whole time. The 05 up Overdrive is not a big thing to me nor is the 07 up electronic controls for the fuel injection. I had 54,000 miles on my 2003 650 before I used the wrong oil in the (reduction) Transmission and it broke. Do not use 0W20 oil in the trans.
I have ridden so many BIG bikes and as I get older and with a few crashes behind me I may need to downsize in a few years. I still have my crashed 1981 Goldwing 1100i with the Hondaline bags, trunk, a Vetter Windjammer fairing and loads of chrome parts. It tips the scales at 910 Pounds wet, 1100 pounds with me on it when I crashed in Oct 2010. I have since crashed a 2008 Burgman 650, Dec 2011.
Someone else may chime in here. Like our resident 400 Guru saying "GET ANOTHER 400". :twisted:
