I am not sure which size setup you have, but with the 2009 TMEC it gets confusing; the most popular seems to be the 17"/17" motard. They also had what I believe were 17"/17" knobbies, and finally the 21"/18" common-for-enduros setup with knobbies. If you have the 21"/18" setup, I would guess you could find a replacement with other Chinese enduros, if not Hondas? If you have relatively cheap mid-2000s Chinese enduros on Craigslist, perhaps check a couple out to see if the wheels are useable.
