The rotor wasn't too very good either... just scored a brand new Yami rear rotor for $138.57. May not have been any great bargain, but my bike is an '01, and a new Yami rotor, the way I use the rear brakes, ought to last the rest of my riding days... so, for me, I see it as a smart value!
Where did you find the deal on the rotor? I was looking closely at mine and its really grooved up. All I'm finding so far is $170-ish
