Supercross History of BMX

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.
