No one ever sent me the memo on how stressful it is to be a parent of a kid who is racing supercross. I am usually a pretty mellow dude and have been around racing and raced my whole life, but having a kid who is racing in the SMX Next portion of the Monster Energy AMA Supercross series is a lot more than I thought it would be. Just slap on some parts, get stiffer suspension, and let him race, right? Well, the problem with that is that I know too much, and with that knowledge comes some responsibility to give my kid the tools that I think are the best so he doesn't have any excuses. Also, for me, there is a layer of safety that I must implement in his builds so that I know there will be no failures when he's going through a rhythm section or up the face of the triple. Supercross has a narrower window of failure than motocross, so I decided to give you some insight on what I think is the best and safest bike my kid can throw a leg over.
