This is a 4th generation Honda twin spar 250x modified through Service Honda in IL. to become what possibly wouldve been a modern open class 2stroke had the AMA not dropped the 500cc's in the early 90's. This is modern MX tech with the open class power of a 500cc 2stroke. I spent a fortune for the experience of owning this machine, and it was worth it. No longer with me, it was, and probably will ever be, the baddest bike i'll ever have owned.
