How Close Is Carson Mumford's KTM to a Showroom Bike?

How close is a front-running pro bike to one you can buy? We rode Carson Mumford's #71 AEO KTM 250 SX-F at Glen Helen to find out. It runs a Factory Services engine and Factory Connection suspension, but almost every other part on it is something you can buy off the shelf. That's what surprised us most. And it carried Carson to two third-place motos and two fourth overalls this year, the best finishes of his seven-year career. Josh and Dennis break down the setup: the tall Honda-bend bars and wing seat, the one glue-on grip he runs to fight arm pump, the 24mm offset clamps, the 14/53 gearing, and an engine that pulls so far you can barely find the rev limiter. We also sat down with Carson's mechanic, Dillan Stanfield, to talk sag numbers, race-day routine, and what it takes to wrench for a pro seven days a week. Big thanks to Jeremy and the AEO KTM crew, and to Dylan for driving out through two hours of traffic to make this happen. Congrats to Carson on the contract extension. We'll be watching for the #71 on the box. Stick around to the end. Dennis might have taken the bike for one more lap. More at motocrossaction.com.
