Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a noise-reduced brake disk which can effectively prevent brake creaking upon braking almost without deteriorating the designability.SOLUTION: The brake disk 10 for motorcycle includes: an attachment part 11 to a vehicle body; a sliding part 12 with a brake pad P; an arm part 13 for coupling the attachment part 11 and the sliding part 12; and a plurality of pattern holes 14 as a plurality of reduction pores for reducing weight, formed between the attachment part 11 and the sliding part 12; wherein one or more configurations of circumferential arrangement interval, radial arrangement position, and inclination and size for the radial direction of at least one pattern hole 14 with respect to the brake disk 10 are made different from the configurations of the other pattern holes 14, the pattern holes 14 are configured to be rotation-asymmetric, and the amplitude of natural vibration mode due to the pattern hole 14 is reduced.
