Common Issues:
Potential for primary chain tensioner wear (especially early models), occasional issues with starter solenoids, and normal wear and tear on suspension and brake components. Fuel line routing and potential leaks are also areas of interest for this era.
Heritage:
Harley-Davidson, founded in 1903, is an iconic American motorcycle manufacturer renowned for its V-twin engines, distinctive styling, and robust build quality. The brand embodies freedom, individualism, and a rich motorsport history.
Evolution:
The FXSTDI Deuce was introduced as part of Harley-Davidson's Softail family, characterized by its hidden rear suspension that mimics the look of a hardtail frame. The 'Deuce' designation referred to its extended, custom-inspired styling, often featuring a longer wheelbase and a prominent front end.
Production Period:
The FXSTDI Deuce was produced from 2000 to 2007. The 2003 model year represents a specific iteration within this lineage.
