Super1C, I have to respectfully disagree. Do I "know" an all Japan built sled is coming from Yamaha... of course not, but, "IF" there is one coming, my money is on next year as it's their 50th anniversary. Reading CR's blog he hints that they are currently working on future possible builds, so they are still in the game. All of that said, the Sidewinder tech (motor) is just amazing and the new Viper chassis sure does isolate the driver from trail impacts. Those who haven't tried one (VIPER/SIDEWINDER) should, prior to passing judgement. CHEERS!
