Honda Motorcycle Brake Rotor Appraisal

Honda GL1000 Front Motorcycle Brake Rotor

This item is a motorcycle brake rotor, a crucial component of a motorcycle's disc braking system. It features a bi-metal construction, evident from the distinct silver-colored outer braking surface and the black-colored inner hub. The braking surface, likely made of cast iron or steel, exhibits typical wear patterns consistent with regular use, including concentric grooves from the brake pads. There are no obvious deep gouges or cracks visible, suggesting it retains structural integrity, though precise measurement of its thickness would be necessary to ascertain its remaining service life. The inner hub is black, possibly painted or coated aluminum, and features a multi-spoke or 'web' design with approximately 10-12 openings, designed to reduce weight and dissipate heat. In the center of the hub are several precision-drilled holes for mounting to the wheel, and smaller holes are also visible for potential floating pin attachment, indicating it might be a semi-floating or floating rotor design. A notable distinguishing element is the handwritten blue marking 'GL1000 Front' on the silver braking surface. This marking strongly suggests that the rotor is specifically for the front wheel of a Honda GL1000 motorcycle, which was originally produced from 1975 to 1979. This age makes it a vintage or classic motorcycle part. The overall condition appears used but functional, with a visible patina on both the braking surface and the hub, indicative of age and exposure rather than severe damage. The craftsmanship appears to be standard for OEM parts of that era, prioritizing function and durability.
