So the dealer that installed the new tires before the purchase of my new love evidently had a cruel mechanic. He warped her rear rotor nicely and also bent the dust shield on the other side of the rim. dust shield fixed and today I received my new/used rotor. At lunch break we installed the rotor and smooth as glass. Purchased from Fallen Cycles in Daytona Beach FLA. Prompt service and reasonable price $35 for a very lightly used OEM rear rotor.
