I recently purchased a set of galfer wave rotors and break pads for my Superduke 1290gt and only have one little street ride for experience. What I can say is these parts are a good fit and certainly fixed the problem with my front brake lever pulsating. Not sure if the rotors were slightly warped or maybe excessive brake dust was the culprit. However I bought the bike used and the previous owner had the same complaint. So although it's too early to tell of the true value of this product I will say it seems to work great and the wave rotors do add a trick look to the bike. Also bringing the bike more up to date in that regard. Although they won't make it go faster and they are not cheap. Neither is the bike and in that regard I with they came stock as oem equipment like they did on my 05 ninja zx10r or my buddies Kawasaki Concours.
