Mounted up quickly and easily. After taking it easy (with new pads) for the first 200 miles, as directed, I was very pleased with the performance and good looks. While I didn't do clinical performance comparison with the OEM rotor (too many variables where I live), I have every confidence that braking is improved and that the weight savings and modern looks are well worth the competitive price. I wish they had these back in the days of my CB750! Thanks again, highly recommended.
