63SP Harley Davidson 1970-1978 ITALIAN IGNITION KEY BLANK Replacement for key blanks with the a part number of 63SP, FEM-1I, F91FS, ISP2, or F91F. Fits Ignition of your Harley Davidson/Aermacchi from 1970 through 1978. Key Code Series: F1-78 Prior to 1970, the Sprint used a 1041G blank, and starting in 1970, the Sprint, MC-65, SS350, X90 and all the other Italian Harelys used this 63SP "F" Code key like the other small HD 2-strokes. You can see a few other keys Harley used in pic #4 (in the Orange Box). I stock most early Harley keys in my store. 1969 Model year owners: I had the owner of a 1969 350SS report his bike used the 63SP blank, so 1969 bikes might have split between the 1041G and 63SP blanks. Beware and compare pics! Also may fit some other Italian 60's-70's era two-strokes/scooter/moped brands (match your key part number prior to ordering!). This blank also works on ignitions of some Outboard Motor Corporation (OMC) outboards made by Evinrude, Johnson, and Gale. The BRICKLIN car company used this key blank on their DOORS for their short run from 1974 through 1976. I currently have the Italian fork lock keys still in stock, as well. Check out my Store! If you have an American based big twin Harley, I stock the original Briggs and Stratton OEM key blanks. See my ebay store! If in doubt, don't hesitate to send me a pic of your current working key, I would be glad to assist you. Many thanks go to Guy Puleo at Sonny's Motorcycle Repair in Lowell, MA. This shop has specialized in Aermacchi-based Harley repair and renovation for 35 years, and I relied heavily on their knowledge regarding Italian Harley keys.
