A motorcycle weighs 1/4 the weight of a car. And have you ever measured the diameter of a brake disc off a motorcycle compared to a car? Bike discs are HUGE and have enough surface area to keep cool and to be drilled.
As I said nowadays cross drillled rotors are a waste on CARS. Pads don't gas as much and hit hurts the intergrity of the rotor UNLESS the holes are CAST into the rotors. Ever see a rotor shatter while on track? It's not nice.
