Audio System:
Some Dyna models offered optional or integrated audio systems, typically AM/FM radio with CD player or auxiliary input, often with handlebar-mounted controls. Many riders opt for aftermarket audio upgrades.
ABS:
Anti-lock Braking System (ABS) was available as an option on many models, enhancing safety during braking.

Manufacturer:
Harley-Davidson Motor Company, founded in 1903, is an iconic American motorcycle manufacturer known for its cruiser and touring motorcycles.
Dyna Lineage:
The Dyna platform was introduced in 1991, evolving from earlier Big Twin models. It was characterized by its traditional styling, rubber-mounted engine for reduced vibration, and a distinct frame geometry.
2009-2012 Updates:
This period saw the widespread adoption of the 6-speed Cruise Drive transmission across the Dyna line, refinements to the Twin Cam engine, and the introduction of electronic fuel injection as standard. Model variations like the Fat Bob, Street Bob, Switchback, and Super Glide Custom were prominent.
Production Status:
The Harley-Davidson Dyna line was discontinued after the 2017 model year, with its successor models largely integrated into the Softail lineup.
