The Harley-Davidson FLSTF/I Fat Boy, a true icon of American motorcycle design, returns for 2004 with subtle yet effective updates to its already impressive appearance.
With the Twin-Cam 88 motor now under its sleek tank, this “Big Custom” machine exudes a commanding presence on the road. Its smooth power delivery is matched only by its imposing stature, featuring fat forks, a 16-inch front tire, and broad handlebars that demand attention from all who pass by.
From its menacing shotgun exhaust to its luxurious leather-laced seat and tank panel, every detail of this bike screams “style” – yet it’s the Twin-Cam 88B engine’s effortless power that truly sets the Fat Boy apart.
