As fate would have it, Justin had a 2003 KX250 two stroke that he was just starting to assemble and it didn’t take much deliberation for us to come to the conclusion that racing a two stroke sounded like a lot of fun. Justin delivered the bike to Precision Concepts and a couple weeks later we had a race bike. We couldn’t wait to start burning laps on it.
