I have never ridden a 700XX. But I rode a 2010 SE Big 3 700R, Barker duals, PCV, AutoTune, and Amsoil Intake, open box. AMAZING! The owner has raced XX's and has beat them. They are extremly heavy, and have the same motor specs (686cc) and IMO, the 700R looks WAY better. You can get alot of used parts for great prices, because there are so many of them.
