Part: Brake rotors

Video tutorial

To replace the discs on a Husqvarna SM 125, start by removing the front wheel by unscrewing the bolts at the bottom of the forks and the nut holding the wheel axle. Once the wheel is removed, unscrew the four Allen bolts securing the disc to the spokes: before replacing the disc, remove the speedometer and mount it on the new disc, as shown in the video.

Before repositioning the wheel with the new disc, also replace the brake pads by opening the brake caliper. Once the pads are replaced, you can remount the wheel and caliper and follow the same procedure for the rear wheel.
