Brake Rotor Appraisal

Motorcycle Brake Rotor

This item is a motorcycle brake rotor, characterized by its circular, disc-like shape. It appears to be constructed from a metallic alloy, likely steel or cast iron, given its greyish-silver color and the typical material used for such components. The rotor features a series of circular perforations (holes) around its outer circumference, designed for heat dissipation and weight reduction, which are common in performance or custom brake systems. Internally, a distinctive, sculpted design with three swirling cutouts adds to its visual appeal and further contributes to cooling. The central hub area is raised and equipped with five smaller, evenly spaced holes for mounting bolts, and a larger central bore for fitting onto a wheel hub. Visible condition issues include significant surface wear on the friction surfaces where brake pads would make contact, indicated by circumferential scoring and discoloration. There are also areas of black residue or grime, particularly in the central hub and intricate cutout sections, suggesting age, use, and a need for cleaning or refurbishment. There are no clearly discernible manufacturer's marks or signatures visible from the provided image. The design, particularly the swirling cutouts, suggests it might be an aftermarket or custom-style rotor rather than a standard OEM part, possibly dating from the late 20th to early 21st century given its design elements and apparent material finish. The craftsmanship appears functional, with clear signs of real-world use.
