V Twin Pulley Appraisal

Harley-Davidson Motorcycle Wheel Pulley (Part No. 40289-R1)

The item is a gray, circular motorcycle wheel pulley, likely made from cast metal, possibly aluminum or a similar alloy, given its appearance and weight-saving design with circular cutouts. Its approximate diameter appears to be around 10-12 inches, consistent with a power transmission component for a motorcycle. The pulley features a central hub with five precision-drilled bolt holes, indicating where it mounts to an axle or wheel assembly. Surrounding this central hub, there are seven larger circular openings symmetrically spaced, designed to reduce the overall weight of the part. The surface of the pulley shows a matte, slightly textured finish, characteristic of a casting. Visible markings include 'HD' (likely signifying Harley-Davidson) and a part number '40289-R1' which is etched or cast into the surface, confirming its origin and specific model compatibility. The overall condition appears used but functional, with no obvious signs of significant damage such as cracks or major deformations. There is some surface grime and minor scuffing consistent with regular use and exposure to engine bay conditions, but no deep gouges or signs of excessive wear on the teeth (though the teeth themselves are not clearly visible in this top-down shot). The contrasting bright, machined surface of the central hub suggests tighter tolerances for mounting. This is a functional, durable component designed for transferring power, indicative of a part from the late 20th or early 21st century given the part numbering convention and material. The craftsmanship appears robust, as expected for a high-stress motorcycle component, with attention to weight reduction and precise mounting.
