I recently purchased a pair of front brake rotors from one of the members on this site and noticed that they are different than the ones on my R. In the photos, the one on the left (stock number 44343-01) is his and the one on the right (stock number 44553-06) is the one from my R.
Although the discs have the same bolt pattern, they have different diameters (44553-06 is 11-3/4", 44343-01 is 11-1/2") and the pad surface hieght of 44553-06 is 1-3/8", 44343-01 1-5/8".
My concern is that from looking at the wear pattern on my original discs (44553-06), and the discs I bought (44343-01) having a slightly smaller diameter, the pads will not have full contact with the 44343-01 discs.
Your thoughts?

brembo(06 up) discs are larger than the non-brembo(02-05)

Yup, pre 2006 bikes with Kelsey Hayes calipers have 11.5 inch, 292 mm diameter rotors just as Sportsters, Stuporglides and Soft Tails do, while bikes with Brembo calipers have 300 mm diameter rotors.
Galfer offers a very nice wave rotor for our bikes that mounts to the stock mounting points. Very light and very trick.

Thanks phil. Actually, I spoke to the guy I purchased the rotors from last night. It seems he just grabbed the wrong set of rotors and sent them to me. Honest mistake. He's shipping out the '06 R rotors to me today and I am going to try to sell the 11.5 inch rotors he sent to me earlier on eBay and send the proceeds to him.
