Imagine your Yamaha YZ125 ripping around the track, shredding every corner, and catching big air. But let’s be real—after countless rides and maybe a few too many days left out in the rain, your YZ125 is looking… well, a little “lived-in.” The graphics are peeling, the seat’s got a couple of scars, and the plastics are as faded as a sun-bleached beach towel. It’s the bike that’s seen it all, and it wears that history proudly—but now it’s time for a refresh.
