2003 Harley-Davidson FLSTF/FLSTFI Fat Boy, EFI Fat Boy has Forward Controls, V&H Exhaust, Stage 1 and More - 100th Anniversary FLSTF/FLSTFI Fat Boy Like all Softail models, the Fat Boy is powered by a counter-balanced Twin Cam 88B engine. It cranks out big, juicy torque and comes with carb or sophisticated EFI. What you dont see is a hidden rear suspension that provides classic looks and a great ride. The styling comes courtesy of a high-calorie diet of iron and chrome. Note the burly FL fork and big 7" headlight. Solid disc wheels. Fat rubber, now 150mm wide on the rear. Giant fenders. Floorboards big enough for behemoth-sized shift-kickers. We went large with Anniversary details. Gold-trimmed tank cloisonné. 100TH Anniversary emblems on the seat and engine covers. Its the Fat Boy in formal wear. Size XXXL, of course. * MSRP may not reflect vehicle shown. See Additional Features for specific color/option pricing.
