Supercross SX250 Frame

Supercross SX250 Frame 24 to 26 or 29" (22" Top Tube on the 24")

This is the Supercross SX250 Frame 24 or 26 and 29" description

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

During the SX250's design process, the Steel Mills were limited on tube sizes. So to solve the issue of frame flex, we added additional triangulation. By lowering the first set of seat stays and adding the second set of stays, we increased rear-end rigidity. This produced a stiffer, faster-accelerating frame, that still rode smoother than other options on the market.

Since we discontinued the 6-bar rear end, we always get asked about doing a re-issue. In 2019, for our 30-year anniversary, we did a limited run of 6-Bar SX250's . But this was no old-school wall hanger. Rather an actual modern race frame with a retro aesthetic. We brought TANGE back on board to build a few more Prestige® Tubesets for the ultimate Retro Race bike. There were only 30 pcs of each size!

Since then, we've had a ton of people ask us to do it again. But this time, they wanted the 29" frame set.

Introducing the SX250 6 Bar Chassis Kit - A Reynolds Cro-mo version of our original 6 Bar frame in a 26" Pro! We're also bringing back the popular 24" Pro XL Cruiser.

Each chassis contains:

• Supercross BMX SX250 Frame Reynolds® made of Butted Cold Drawn Cro-moly Steel

• Heat Treated 4130 Seamless Cro-mo Supercross Pro Fork with Welded in Star Nut

• Speedline Sealed bearing Campy Style Integrated Headset.

We get asked for the SX250 as much as the Vision F1, and we are humbled that people now love our original 6 bar design more now than when we released it 35 years ago. I know it seems like the last few anniversary's or "RAD"averserary's we have been bringing back the "6 bar" the classic SX250, but each time it was limited runs. 10 pcs of this, 33 pcs of that, and each one was unique, so each one is a collector edition in it's own right. And this time we are doing it again. If you look closely, not only is the 6 bar back, but this is the first time we have gone back and actually re created the original "Fish Head " Star Products dropout for this 35 pc , 35 year anniversary edition. Yes you read that right. 35 pcs of each of the 3 sizes. 20" , 26" and of course the 29".

If you were at Dirtyfest 2, you saw Camel Joe - Josh Randall on the prototype of this variant of the SX250, serial #001, and was track testing it in the California Sun and having just as much fun as we did 35 years ago. Ryder Merki was shredding up one of the Original SX125 Pro Frames , and Kylie Martin was tearing up the track on the 30 year anniversary SX250 Prototype. lets say that there was a lot of SX250 Action going on at Dirtyfest... after all, that is where a BMX bike belongs, in the dirt, with your friends.
