This isn’t just a CR125 stuffed into a CRF150RB. Over on my YouTube we break down this build and everything that went into it. The frame and swingarm was cut up to get modern geometry. It has a fully hand made custom air box to keep maximum air volume for the 125 air boot and filter. A hand made aluminum gas tank that will make a 30 minute moto. A custom pipe to make sure it didn’t loose any power. Massive thanks to BBR Motorsports Duane Brown for making this happen from the ground up. @Red Bull USA for supporting the build along with @Honda Powersports @MotoSport.com and @All Balls Racing. Dubya did the wheels, Dunlop tires, Bud Racing triple clamps, Renthal bars, grips and chain, @Backyard Design graphics with a @Guts Racing seat, Bolt Motorcycle Hardware bolts and washers, Hinson with the clutch, a @Lectron Fuel Systems Billetron, @Maxima Racing Oils fluids, and everyone else who made this happen. We did a similar build a few years ago with a YZ, but which brand of supermini 125 would you like to see us b
