The 2020 Yamaha YZ450F may look the same but received many updates that can be seen upon further inspection. We give you that closer look on this episode of “The ’20s” video series. Dirt Bike Magazine was invited to Milestone MX Park in Southern California to test out the new 2020 Yamaha model. This bike features a new air filter, new rigidity characteristics in the frame, more rigid triple clamps, smaller head profile, new brake pistons, new denser seat foam, changed handlebar position, new exhaust header, new handlebar mounted map switch, and much more. Check out what Managing Editor Mark Tilley had to say about our first day of testing on the 2020 Yamaha YZ450F.
