Yeah, and those stock ones are 'spansive too. As mentioned already EBC makes some good rotors, especially for the money. Prolly not wave rotors though.

AMEN, I R&R Pete's K 75 with EBC semi floaters, quite impressive over the BMW OEM stock rotors.

You are correct the EBC's are NOT a wave design, NO BIG deal, wave design is purely cosmetic in function.

FWIW, the pulse may clear up if you practice hard braking. Changing to a different brand of pads is another suggestion.

FunKy front wheel bearings can also mimic a pulse.

I happen to have a spare pair of stock front ABS rotors in my parts stash. Take off from a rear ended K 100, like new condition. Tempt me with a reasonable offer.
