YZ 125 lowering and what to do with the front forks

As for the front: our super simple install instructions gives a starting point and some guidelines for raising the front forks based on personal preference and final rear sag setting. There is no 1:1 ratio since changes to rake/trail affect the geometry at a different rate than changes to the rear suspension. After lowering the YZ 125 suspension in the rear we recommend a starting point of about 4mm when sliding the fork tubes up in the triple clamps.
