I have an '18 Beta Xtrainer. I just installed a FMF Gnarley pipe and used the FMF Q-2 S/A. This is my first ever Beta. The bike is stock except AMP suspension, protection, fuel tank, pipe & silencer, air box mod and a JD Jetting kit. I just wanted to say that if the 300 RR is a better edition of the 300 than my bike is now.
That is a great machine! because this bike with changes is awsome! I couldn't be happier with how it acts.
