Re: Brakes (tech) Slotted vs X-Drilled

[Kevin <aventari@cts.com>]

Yeah, but how come high performace motocycles use crossdrilled? The
x-drilled rotors can't be Satan's spawn as the slotted advocates would put
forth, but then again a motorcycle is different from a car. All 4 of my
brothers bikes are xdrilled. 93 Ninja Zx-6, 91 VFR 750, 94 Honda SR-250,
and an old 78 Yamaha 400. But none of them are axially vented like our 84+
rotors are. to save wieght i'm sure.
