Supercross BMX | AMX250 - Cadre de course BMX anniversaire 35 ans - The Six Bar

Mirror Polished ETA 3 Weeks Til Shipped

  • Overview

  • Geometry

Back in 1989 when we started Supercross BMX, the original frame was our 6 bar design. We used this design for over a decade on our Cro-mo and Aluminum BMX race Frames. 

When we designed the SX250, we were limited on tube sizes that the Steel Mills were running. We had to solve the problem of frame flex and stiffness, so the extra triangulation was our solution. By lowering the first set of seat stays and adding the second set of stays, we had a frame that was stiffer, faster accelerating, and better handling than the others.

We eventually turned the SX250 into the AMX250, the Aluminum Motocross!! And for our 35 year anniversary, we are bringing them back in Limited Editions and Limited Sizes for the BMXers in all of us that love the historic BMX racing. 

 

All frames will have the 35 Years Behind Bars Retro decals.

And don't forget your Supercross BMX Retro Pads, or the Supercross BMX Retro Stem to complete the build. Who could forget the fork?

Please post pics of your builds and share your serial # on the Supercross BMX Riders Group on Facebook!

Full 6061 T-6 Aluminum for the historic Aluminum ride and feel, they then go through a double heat treat process from T-4 to T-6 with a final alignment process to ensure a strong and straight frame . The Extra Stiffness, the weight reduction, the speed, the style. the BMX!
