Excellence all around as my review shows, with the following caveats:-
To the manufacturer & supplier to follow up on;
The rotors are top notch the supplied allen bolts, washers and nuts to secure the rotors to the aluminum cast hubs (on my BMW r65LS), were well below tensile strength for such a purpose and the washers were too large both for the bolts and their purpose, they binded on the calipers.
M/C Superstore supervisor was proactive when I called in after waiting four days for a response from the service desk, he gave me a $25 credit toward my next order, along with an apology.
Great company to deal with....
I went out and bought new grade 8 bolts for the job, all's well.
I installed these same brakes 20K miles ago and they still perform beautifully.
Problem is I recently ordered two sets for the front wheel this time around and both were for the same side. I saw no check box for Right or Left on the Web order page so had to assume that the packaging person would pack one of each. I haven't called yet to correct the shipment but I will. Maybe it was something I missed when ordering?
As always motorcycle Superstore sent it out fast. Great company them self's.
As for the rotor it's freaking awesome. I put it on 02 car600 f4i. Does what it's supposed to do and better. Only have 500 miles on it so far. But it's working great. Exact fit. Doesn't over heat. I can actually touch it after riding. Great breaking power. So much better than stock. And looks awesome too.
I would definitely recommend to anyone.
