Harley Davidson FLSTF Softail Fat Boy 2013 Service Manual

The standard 2013 Fat Boy carries forward the same fundamental Twin Cam 103 formula, but this exact model year sits alongside a genuine limited-production sibling worth knowing about: the Fat Boy Special 110th Anniversary Edition, capped at just 1,750 units worldwide, celebrating 110 years since Harley's 1903 founding. That anniversary trim added an exclusive Anniversary Vintage Bronze and Vintage Black paint scheme, solid bronze tank medallions plated in black nickel, a chromed timer and derby cover with a forged solid bronze trim ring, and an individually serialized authentication plate on the center console — genuine collector-grade detailing distinct from the standard-production Fat Boy.

Power comes from the High Output Twin Cam 103, an air-cooled V-twin displacing 1,690cc, delivering a claimed 133.8 Nm (98.7 lb-ft) of torque at 3,000 rpm through a 6-speed transmission with belt final drive. This exact 2013 model year carried the same fundamental Fat Boy formula that had defined the platform since 1990: bullet-hole solid-disc aluminum wheels, deep valanced fenders, a horseshoe oil tank, and full floorboards.

Standard equipment included Electronic Sequential Port Fuel Injection, and the 110th Anniversary trim specifically bundled the Smart Security System and ABS as included equipment rather than optional extras — a real distinction from the standard 2013 Fat Boy, where those features carried an added cost. Harley's own 2013 press materials confirm ten different models across the whole lineup received this same anniversary treatment that year, each strictly limited in production to preserve exclusivity.

This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 2013 Softail Fat Boy FLSTF running the way it was built to.
