I'm looking for a 2nd rim so I can always have two sets of tires ready to roll (one for mud and one for rocks). There are very few used TTR rims available on ebay because it's such a rare bike. Is the TTR rim interchangeable with any other bike rim, like a YZ?
I have a suspicion that anything WR/YZ from 1992-1998 will fit. However, I cannot say whether or not it will be a bolt-on fit or spacers would be needed. Bear in mind that the YZ rims are 19''. There may be other models that should fit also, see more here- http://ttr250.activeboard.com/t55314054/wheels-from-wrs-19921996-may-fit-ttr250/
I will remind you once again that I do not know whether they fit for sure but they all use the same diameter axle at least.
