Brake rotors for motorcycles

Abstract

The present article is a brake rotor to be attached to a motorcycle. The present article is formed of a central annular portion having a large hole formed in the center, an outer annular portion that is one size larger than the central annular portion, and a plurality of rod-shaped portions extending radially from the central annular portion to the outer annular portion. The outer annular portion has two rows of small holes, one inside and one outside, formed on the circumference at a predetermined interval, and protrusions with small holes are formed on the inside of the annular portion at a predetermined interval. The protrusions are shaped to protrude on both the front side and the back side, and a stepped counterbore is formed around the small holes. The radially extending rod-shaped portions are connected by an annular frame that connects the outer ends of the rod-shaped portions, and the annular frame is joined to the inside of the outer annular portion. The central annular portion has small holes formed on the circumference at a predetermined interval, and a stepped counterbore is formed around the small holes.
