Did you all know? I just figured this out browing through Yamaha Japanese website. http://www.yamaha-motor.jp/mc/lineup/sportsbike/index.html This includes not only WRR & WRX but also Serow 250, XT250X, and tricker. Just to clarify, U.S. XT250 = Japanese Serow 250, Japanese XT250X is the motard version, and tricker is the same chassis but smaller wheels, tank size, etc. How come U.S doesn't get fuel injected XT250? And guess what? All these models have been getting fuel injection since 2008, but I would be surprised if 2010 US XT250 gets FI. talk about fairness.
