About the Brake Rotor / Disc
This is a Magura Storm HC one-piece rotor in 203 mm, 2 mm thick and 6-bolt, which our catalog lists as the stock rear size on the 775 MX. A one-piece steel rotor is simple and tough, and it works with Magura MT5 pads. Swap it when you see warping, heavy grooves or a rotor that has worn thin. Rotor bolts come included. Check which rotor size your rear caliper adapter is set for before ordering.

Install notes
Remove the rear wheel and undo the old rotor bolts. Clean the hub face, fit the rotor with the arrow facing forward rotation, and tighten the supplied bolts in a star pattern to Magura's torque spec. Check the caliper is centered, then bed in new pads.
FAQ
Does this rotor fit the front of a 775?
It is sized for the rear. The front on the 775 uses a larger rotor, so check your caliper adapter and the size of your current rotor before swapping.
