I bought this wheel off eBay to adapt my YZ125 to dirt track, but then decided it was too much time and effort for the outcome so bought a brand new aftermarket wheel complete. Now, I've got one too many 19" rear wheels. Cost me $225 in total, but yours, postage included, for $175. It looks clean and tidy, a few small nicks, but generally straight. No disc or sprocket. Bearings are good, but dust seals could do with replacement. Here's the original eBay ad text:
"Up for auction is a genuine Yamaha rear wheel assembly from a YZ250 2010 model two-stroke. This wheel will suit pretty much all of Yamaha's YZ and WR range from 1999 through to 2011 (please see the listings below for correct fitment). This wheel is in very good condition with only minor scratches on the Excel rim, and has only been used for about 20 hours worth of riding!"
