Harley Davidson FXSTD/I Softail Deuce (1999 – 2001)

The 1999-2001 Harley-Davidson FXSTD/I Softail Deuce is a masterpiece of American motorcycle design. Its potent V-twin engine boasts a 40mm constant velocity carburetion system, providing a rich and responsive throttle feel.

Underneath its sleek lines lies a rigid frame design, significantly stiffer than previous models at 34% more rigid, delivering exceptional handling capabilities. The elongated fuel tank and straight-line rear fender contribute to its distinctive style.

Its ESPFI electronic sequential port fuel injection system ensures seamless delivery of power from the chrome-topped “fathead” motor.
