Ryan Haygood picked up a new 26 YZ450f and suspension was his first upgrade?? Why, because most production settings and springs don’t work for everyone there’s a small window that it does. Buying a pipe, motor work, or other accessories aren’t going to make you faster or a better safer rider! Suspension will!
