The FLSTF, or "Fat Boy" continued its run of popularity in 1997. The wide "beach bars" were still used, as were the solid wheels at both ends of the low-slung FL. Cosmetic changes were the only revisions to the 1997 editions. But with a runaway success, why mess with the formula? The original all-silver motif had been replaced in 1991, and every year saw different hues being applied to the sheet metal of the Fat Boy. The winged tank trim remained the same.
