4XL BMX Racing Frame?! 2025 Vision F1 Updates

We all know and love the classic Vision F1 racing chassis. It is stiff, lightweight, and one of the fastest bikes that Supercross, hell, one of the fastest bikes that ANYONE has to offer. You know that at Supercross BMX, we are always building bigger and better things; introducing the 4XL Vision F1 racing chassis.

The size of this bike is long awaited, and we are so excited to finally introduce this. Kye White and Oliver Moran are off to the World’s on theirs along with Justin "Dr.J" Perkins, and Gaige Gomilicke has already won a few Pro/AMS on his, so it is time to join Vision F1 family.

One of the most notable features of this bike includes an updated bottom bracket, which will be  the new standard bottom bracket on Vision F1s for 2025 and going forward. We will be running a 68mm T47 bottom bracket, which is a threaded bottom bracket, but it uses a larger bearing.

The T47 BB came about after years of frustration with the Press fit BB shells that others use, and to allow a larger bearing for smoother cranking and better power transfer. While many have had different ideas, the guys at Chris King developed this and made it an open source standard for the world to use (thank you guys) as it really does offer a true performance advantage.

Your cranks will be smoother and more stable than ever before! This offers a better power transfer, so all of the work you are putting in will shoot you straight down the track!

We will have the T47 bottom brackets on https://supercrossbmx.com soon so you can get it for a 19mm spindle for a traditional profile crank, a 24mm spindle, or a Speedline crank with a 30mm spindle. This is the future of the Vision F1! Or as some of the fans on our YouTUBE like to call it, the #Re-Vision.  Whatever you call it, you will want to call one yours.
