Back in Nov. I gave $1700 for a 2001 WR426. It still had the original tires in decent shape too, looked like it was NEVER dropped and came with bark busters, FMF Powercore
, frame guards and a few other extras, this was by far the cleanest used dirt bike I'd looked at out of 15 or so. The guy had it on consignment at a local shop all last summer for $2300. At the end of the season they told him to come get it, I stopped by the shop looking for a bike and they said they knew a guy who had a nice one for sale. Went over and looked at it and offered him $1700 he said NO less than $2000. I said okay, good luck selling it! About an hour later he called me up and said he'd take my offer.
Hope that helps! You may be able to get around $2000 since it's more in season now. Mine is not plated either.
