Supercross SX450 Bubba Harris Edition BMX Race Frame

The SX450, it started out as a Cr-mo BMX Race Frame that evolved from our UL series, & quickly became Bubba's go to bike, so why not give the 2023 Hall of Famer, 3 time ABA #1 Pro & UCI World Champ a signature bike of his own. He calls it his Fun Machine. He rides at the skatepark, the trails, the track, it goes everywhere he goes, & after all, isn't that what your bike should do? 

It is an instant classic & true to form, it's built from Air Hardened Triple Butted Cro-mo. It's also Triple Show Chrome Plated, (got to love Chrome right?) & it even has retro inspired graphics. But that is where the Retro, or Tribute style ends. At the end of the day, it is all modern & probably, the most advanced Cr-mo race frame available.

It starts out w/ a full CNC machined Campy integrated head tube, a Reynolds, double / triple butted air hardened Cr-mo tube set, a Butted & tapered seat mast , a CNC’d Euro BB shell, tapered & butted seat stays, chain stays & back side CNC’d laser cut dropouts w/ 10mm slots & capped stay ends. 

And of course what would all of this Cro-mo goodness be with out a full race pedigree so we build it up in our world famous and World Championship winning, Supercross geometry of the all our Supercross BMX race frames.
