🛡️ Safety Features

Safety Ratings:

Motorcycles generally do not receive the same crash safety ratings as automobiles. Primary safety relies on rider skill, adherence to traffic laws, and proper vehicle maintenance.

Active Safety Features:

Hydraulic disc brakes (front and rear) with solid rotor design for effective stopping power. Progressive rate fork springs and rear shocks for stable handling.

Passive Safety Features:

Sturdy steel frame providing structural integrity, handlebar design to absorb some vibration, and low center of gravity for rider confidence.

💡 Technology Features

Infotainment System:

The 2008 FXDWG typically featured a basic instrument cluster including speedometer, tachometer (optional), odometer, trip meter, and indicator lights. No integrated infotainment or audio systems were standard on this model.

Driver Assistance Features:

No electronic driver assistance features were standard on this model. Safety systems are mechanical (brakes) and based on chassis design.

Connectivity Options:

No Bluetooth or smartphone connectivity. Diagnostics are performed via a proprietary Harley-Davidson diagnostic port.

🔧 Maintenance

Initial Service:

First service typically recommended at 1,000 miles (1,600 km) for oil change, primary fluid check, and general inspection.

Regular Maintenance:

Subsequent services generally scheduled every 5,000 miles (8,000 km) or annually, whichever comes first. This includes oil changes, filter replacements, and inspections. More detailed checks (e.g., spark plugs, brake fluid, belt tension) are performed at higher mileage intervals (e.g., 10,000 miles, 20,000 miles).

Engine Oil Type:

Harley-Davidson SYN3 Synthetic Motorcycle Oil or equivalent API CI-4 Plus or higher rated diesel engine oil (viscosity typically 20W50, refer to manual for exact specification and capacity).

Primary Chain Case Fluid:

Harley-Davidson primary chain case oil or equivalent SAE 90 gear oil (refer to manual for specific type and capacity, typically around 2.5 US pints).

Brake Fluid Type:

DOT 4 brake fluid (refer to manual for specific recommendations and flushing intervals).

Fork Oil Type:

Typically Harley-Davidson front fork oil or equivalent SAE 15W (capacity and specific type depend on fork design, refer to manual).

Common Issues And Considerations:

Some Twin Cam engines of this era may experience primary compensator sprocket wear, oil leaks from the cam cover or primary cover gaskets, and potential charging system issues (regulator/rectifier failure). Routine checks of belt tension and tire condition are crucial. Ignition module or sensor failures can cause running issues. Vibration is inherent and can lead to loose fasteners if not regularly checked.
