If you’re looking to try some optional Yamaha Power Tuner maps below are two we have tried so far that we like. The first map shown is blank but Travis Preston gave this to us for a little more low end excitement since the new ’26 YZ450F is a little more plugged up than the 2025 version. The second map is a setting that I worked on that helps with rear wheel connectivity out of corners as well as pulling power (torque feel) when shifting from 2nd to 3rd gears.
