Can't tell for sure from the pictures, but it looks like plain old steel or cast iron disk rotors to me. With all the other carbon fiber, I would expect to see carbon-carbon brakes, also. That would save another couple pounds.
I bet that the reason you don't see the weight quoted is that it would not be all that much lighter than the published weight of a stock Suzuki. All the Big 4 seem to lie by 20 to 50 lbs, as near as I can tell.
OK so cruisers might be an exception to that dishonesty. No one seems to care that much about being the lightest in the class.
