Safety Certifications:
DOT approved lighting and braking systems.
Braking System:
Dual-piston caliper front and rear disc brakes. Optional Anti-lock Braking System (ABS) available on select models.
Lighting:
Halogen headlight, LED taillight, incandescent turn signals.
Frame Construction:
Steel double-cradle frame.
Instrumentation:
Analog speedometer with inset tachometer, odometer, trip odometer, fuel gauge, and indicator lights. Some models may offer a handlebar-mounted LCD display.
ABS Availability:
Anti-lock Braking System (ABS) was an optional feature on many 2009 Dyna models, improving stopping safety.
Diagnostic Port:

Engine Oil Change:
Every 5,000 miles or annually, whichever comes first.
Primary Chain Tensioner Inspection:
Inspect every 10,000 miles. Replace hydraulic tensioner if worn (common wear item).
Drive Belt Inspection Tensioning:
Inspect belt condition and tension every 5,000 miles or annually.
Engine Oil Type:
Harley-Davidson Genuine SYN3 (SAE 20W50 Full Synthetic) or equivalent API SG/SH/SJ/SL rated motorcycle oil.

Primary Chain Tensioner:
The early style hydraulic tensioner (found in 2009 models) is prone to wear and can lead to noise or damage if not replaced. Manual recommends inspection and potential upgrade to a later design.
Cam Chain Tensioners:
Similar to primary tensioners, the cam chain tensioners can wear, especially on earlier Twin Cam engines. The manual provides inspection and replacement procedures.
Fuel Injector O-Rings:
Can degrade over time, leading to vacuum leaks and idle issues.
Brand Philosophy:
