I would even venture to say that the average street rider wouldn't even use a 10 year old 600SS to its full potential. Prices always go up, but I remember the days of the 600SS being in the 7-10 range depending on what you were purchasing. I guess thats probably why I ride a 14 year old SV650. It does what I need, I still probably don't ride it to the full potential that it could be ridden.
