I ride a Hayabusa - HARD! So hard in fact, that I have warped 7 OEM rotors in the past two years. Track days, and canyon carving were simply too much for the stock rotors - even with after market brake pads and SS lines, so I thought I'd give these rotors a try this time around. I paired them with EBC HH brake pads and WOW what a difference!
I was pondering paying the extra money for EBC, Braking or Galfer rotors, but I'm glad I bought these Driven Industries. I have usedthem on the track a few times, and several HIGHLY spirited street rides. I have REALLY impressed with them since day one. My current front brakes now consist of these rotors, EBC HH pads and SS lines. They have a smooth progressive feel and have PLENTY of bite to stop my 500+ lb bike from 170 MPH - and no more warped rotors!!!
These were MUCH lighter than the OEM rotors, and I can feel the difference in high speed transitions. That is an added bonus I wasn't expecting.
Because they are wave style rotors, they have a slight "whirring" sound when you are on the brakes, but I actually kinda like it. However I don't feel the "slight buzz near stop" that ZXRocket mentioned.
I cannot recommend these enough! By far the best bang for the buck in aftermarket rotors
