Supercross BMX · Since 1989
Every race frame we have built in 37 years — the stories, the specs, and the riders who raced them. Designed by founder Bill Ryan, starting with one frame built to stop rear ends flexing at the gate.
In 1989 the average BMX frame gave up a quarter inch of chain sag when a rider loaded the gate. Bill Ryan lowered the seat stays, added a second set, and the six-bar Supercross rear end was born. Everything on this page traces back to that frame.
1989–1998. Seamless 4130 chromoly, the original six-bar rear end, and the frames that built the brand — starting with one prototype welded in a day.
The first Supercross frame — and by sheer numbers, the biggest-selling Supercross frame of all time.
1989–1998The Pro-size companion to the SX250 — same six-bar backbone, sized for the Pro class rider.
1993–1994LWR stood for Light Weight Racer — the small-size Supercross line: SX50 Mini, SX60 Junior, SX80 Expert.
1994Our first carbon frame — 23 years before the Envy BLK, and decades ahead of the sport.
1992–1998The 24-inch Supercross — designed for factory pro Todd Steen.
1994The XXXL frame built for AA Pro Eric Jones — who tried aluminum first and asked for cro-mo.
1992An SX250 built up complete as a Team Model — XLT stood for Extra Long Titanium. Todd "Stiffy" Steen's signature bike.
1992–1994The entry-level Supercross race bike — same full-chromoly frame and fork as the Team model, ready to race out of the door.
1994The first Supercross signature frame — Tange Prestige Ultra Strong with a fluted downtube. Only 2 ever made.
1995–2000. The AMX line brought high-ceramic 6013 aluminum blends to BMX racing when the rest of the industry was running standard 6061 T-6.
The SX250 reborn in aluminum — AMX stood for Aluminum Motocross.
1995–2000The Pro-size AMX — six-bar aluminum for the Pro class.
1995–2000The 24-inch AMX — aluminum for the cruiser class.
2002–2005. The frames that restarted big bike racing — the Quads built with Scot Breithaupt's blessing, the Azusa and its aluminum No-More-A successor, the 26-inch GJS, and the Fat Man Flyer. Every run was tiny and hand-built.
The first modern 26-inch BMX race frame — 25 built, plus 5 Quad Looptail pit bikes, with Scot Breithaupt's blessing.
2002The one that started it all — 24-inch rear, 26-inch front, looptail, built from Scot's own OM Flyer geometry. Two made.
2003A modern JMC — named for the city JMC was made in. Chromoly, built in 20 and 24-inch.
2004The aluminum Azusa — just like Nomura was the aluminum JMC. About 39 ever built.
Mid-2000sA 26-inch GJS built for Jeff Utterback — 25 made, on Scot's personal OM Flyer geometry.
Mid-2000sA 26-inch tribute to the FMF and Race Inc — 25 built across the two styles.
1999–2008. DEVO and UL cro-mo, the G6 aluminum generation, and the Easton partnership that produced the scandium S7 — the lightest production BMX race frame in the world at its launch.
The cro-mo series that carried the Supercross rear end into the 2000s — secondary seat stays, flipped.
2002Triple-butted cro-mo with post-weld heat treatment — steel, refined to its limit.
2002–2008The aluminum line after the AMX — from six-bar beginnings to the G6 wonder bike.
2002–2006The sixth generation — Supercross aluminum, welded in Southern California.
2006–2008The UL, re-imagined — Campy integrated head tube, ovalized tubes, and two years of Dew Tour, ABA, and NBL podiums under Aaron Johnson.
2006–2009The G6, enhanced — Easton EA6X tubing and the start of the Easton partnership.
2008–2009The lightest production BMX race frame in the world — built for the first Olympic BMX cycle.
2009The R-CR refined back to subtle — butted round tubes, bi-oval down tube. Mikey Brabandt's frame of choice.
2009–2019. One platform, four landmark frames, and the start of a record run of USA BMX Golden Crank Bike of the Year awards.
S7 performance at half the price — the frame that started the Golden Crank run.
2017–TodayRace Series 7 — the stiffest Pro-size aluminum frame Supercross has ever built. Still in the line today.
2014–2019The first production Supercross carbon frame — and the first carbon race frame to win the Golden Crank.
2019–TodayT1100-KS carbon, titanium-insert dropouts, and a threaded BB — the BLK, upgraded everywhere it counted.

2004–today. The other side of Supercross — dirt jump, park, trails, 4X, pump track, downhill, and enduro frames, built with the same race-bred engineering as the frames at the gate.
The Supercross trail frame — and its MX26 version was the first Supercross 4X frame.
2004–2007The park and street frame — shorter rear stays, thicker dropouts. It became Ben Snowden's Disciple, and its DNA became the Passion.
