The 2021 Yamaha YZ450FX is pretty all new with most of its upgrades coming from it’s other sibling, the YZ450F. The chassis and engine are a step in the right direction, but that didn’t stop us from trying to get both to work in harmony even more out on the track and trail. These two maps are some of our favorites with the last one developed over the course of a couple weeks out on a couple moto tracks as well as some tighter, technical, rocky terrain. If you want to try these maps make sure to have the “POSITION” set correctly on the side of the grid. Some of those numbers have changed on the “Keefer Connection Map”. Enjoy and let us know what you think!
Try this map if you’re looking for less hit with added rear wheel traction.
Looking for a broader pulling power but with more rear wheel connection
