Man honestly the value of the REAL R's have gone down significantly. I recently tried selling mine due to not enough time to ride it as I would like but after trying to sell it for $4500 with no bites I figured I will keep the ****er forever because of the fact that I have 11K invested and I am sure as hell not selling for less. I would say your bike is worth about 6-7K but that is a biased opinion considering I own an R and know what sweet quads they are. If you can't get that out of it I would just hold on to it for a year or so until the hype of the new four strokes go down then try selling it again.
LONG LIVE THE 250R!!!!!!
AND YES IT IS STILL NO 1!!!!!
