Lightest ZX-14 Rotors?
The stock rotors are pretty light. Are there any lighter ones out there, short of sending the stockers to DME?
I think the Galfer's are heavier than stock....

Bill Eason is running lighter ones on his bike, I am not 100% positive, but I think they are brembo standard (nonwave) rotors.

If you change out your rotors, I need one for the extra rear wheel I've got.

I'll keep that in mind, I should be selling my rear rotor within about a week.

I suspect the lightest would be the rotors MotoGP bikes use made of carbon-
MotoGP teams use disc brakes on their racebikes, technology which first emerged in the 1970s and has been in development ever since. Early versions of these discs were steel only and did not work very well in rainy conditions, but were later developed to produce progressive braking in both the wet and the dry.
Now, conversely, steel disc brakes are used by MotoGP teams only in the wet as they have a more modern and efficient solution to be used on dry tracks – carbon brakes.
The benefit of carbon discs are that they weigh 750g to 800g for the same diameter as their 1,200g to 1,600g steel discs counterparts. These figures may seem trivial but where cutting edge racing technology is concerned the half kilos soon add up.

Might wanna look at these if you have a small pile of money lying in the corner:

Not sure of the weight but they look pretty tiny.

I was thinking about letting DME cut my stock ones. They also are not that high to get them cut.

Here are the lightest I've found...
http://www.braketech.com/sportbikes/AXIS-StarBlade-CMC-Rotors.php
$1190 each. Probably about 1/2 the weight of stock...
Cha-ching!

Shane could've just told the BST dealer "please throw a set of these rotors in"

Cast iron is supposed to have the best friction and thermal characteristics of all the metal rotors.

I bet DME cut stockers are the most cost effective option.

Dont plan on using cut down stockers on any kind of fast street riding though. The stock ones have a bad enough time keeping from overheating/warping without losing any more critical mass! Brakes directly convert kinetic energy into heat. Period, thats all they do. The brakes ability to dissipate heat is directly proportional to its braking ability: as metal heats up it loses its ability to transfer heat from the contact area, superheating the contact area (glazing) and ultimately warping the rotors as that overheat condition spreads throughout the rotor.
Rotor design (wave, cross drilling, slots, even the latticework coming up from the floating pinlocks) is all focused around dissipating and/or heat sinking heat generated from braking. It is why Superbike brakes are way thicker and heavier than stock - they arent allowed to use carbon/carbon.
The ultimate goal is to send the heat to the air, which carbon and aluminum excel at. Steel not so much, hence all the effort to increase the surface area of the rotor with waves, slots, holes and such on the steel rotors. Ever see cross drilled carbon discs? Not needed. So if you start cutting the stock ones remember that are directly reducing your braking heat sink!
Oh, cast iron's surface roughness is why it works great as a rotor material. Too bad every other aspect of it makes it horrible as a rotor! Carbon Fiber discs are even rougher, which equals more grip for the pad.
