Perhaps the biggest concern I hear year after year from parents is the legality of our "Bar Risers" in stock AMA competion. Our bar risers are handlebar mounts. The rules state that you may alter your handlebar mounts.
This can be found in the 2021 AMA Motocross rulebook in Chapter 1, section 1.2 under paragraph 7a located on page 23. The end of the sentence reads like this "handlebar mounts may be altered"
Our billet aluminum upper triple plate is legal listed under the 2021 AMA motocross rulebook on page 20. under the list of limited class permitted items Upper (top) Triple Clamp.
