About This Product

Brembo Serie Oro floating front brake disc. Stainless steel outer ring and black anodised aluminium carrier. The float lets the friction surface expand under heat without stressing the hub. That prevents disc distortion and keeps lever feel consistent. Drilled surface aids cooling and keeps the pads clean. Built for street use on Harley-Davidson motorcycles. Sold individually.

Manufacturer part number: 78B40891.
