This is a custom cover for the lower Triple Tree for Harley-Davidsons with 39 mm Forks. I believe they were used in the late 1980s. This is a decorative piece for custom application and you may have to relocate your turn signals or other items to utilize this. Please look at the pictures closely of the label and the old catalog that we found this part number in before purchasing. This is new but it is older stock and discontinued so the packaging may not be in perfect condition. Probably a little Dusty.
