The SMT PR-1 Performance 1-piece solid and 2-piece floating rotors are designed to ensure the most optimal braking with a super sleek design concept. All of our rotors are produced from a high carbon 420 stainless steel, heat treated and machined to perfection. All rotors are parallel surface ground to bring you the best rotor to pad contact. This is a full stainless rotor design meaning carriers and braking surface are stainless steel which ensures optimal strength for the aggressive rider.
From the race track to the stunt scene these PR rotors withstand the heat and abuse associated with aggressive riding. These Harley-Davidson replacement rotors will take your stopping to the next level.
If you’re racing where temps are high and you experience hard braking, choose the vented PR-1 rotor. The vented braking surface helps cool your rotor surface and cool your entire braking system. Hot rotors result in a hot fluid resulting in brake fade, which you definitely do not want on a racetrack.
If you are racing primarily in cooler weather, consider the solid non-vented PR-1 rotor your better option, as a too-cold rotor is just as bad as a too-hot rotor.

I run the 13” non vented on my race Harley. I love them!

Rotors
I have ran all brands of rotors and these are some of my favorite to date. I paired these with my og2 wheels on my Indian challenger in the 13” size up front and 11.8 size in the rear. Extremely smooth braking and no sight of warping. Extremely strong carriers and the buttons showed no wear after 15k miles. Definitely will buy again!!
