Is this the world’s greatest 125 motocross bike? There’s been a huge amount of work gone into it, and now you get to decide!

Yamaha has all but stopped developing their YZ 125, with the modern machines essentially being the same bikes they were a decade ago. So TooFast decided to update their tired old YZ 125 and bring it back to the future to rival the latest KTM and Husqvarna 125s in terms of performance and looks!

There’s been a lot of help to get the bike to this level – thanks to everyone that helped us build this bike. Check out the full specs:
