FLSTF/FLSTFI Fat Boy®
Classic styling combined with modern engineering.
Like all Softails, Harley's Fat Boy is now available in either carbureted or injected models.
One improvement not limited to the Softail series involves a change to the oil system. All 2001-model Harley-Davidson motorcycles filter their oil prior to entering the engine, rataher than upon leaving the engine enroute to the remote oil tank, meaning critical engine components receive cleaner oil.
