Lighting:

Halogen headlamp, LED taillight, turn signals, and brake lights for enhanced visibility.

Frame Construction:

Steel frame and swingarm for structural integrity.

Ergonomics:

Comfortable rider triangle for reduced fatigue on long rides.

💡 Technology Features

Audio System:

Optional AM/FM/CD player with handlebar-mounted controls and speakers. Audio quality and features are basic by modern standards but functional for touring.

ABS:

Anti-lock Braking System (ABS) was a factory option for 2010 FLHR models. The manual details its operation, diagnostics, and service.

Cruise Control:

Electronic cruise control was a standard feature on the 2010 FLHR Road King, enhancing comfort on long highway rides.
