🛡️ Safety Features

Crash Test Ratings:

Motorcycles are generally not subjected to standardized crash test ratings like automobiles. Safety is primarily addressed through design, rider aids, and rider responsibility.

Braking System:

Hydraulic disc brakes front and rear. ABS (Anti-lock Braking System) was an optional feature on many 2013 Dyna models.

Lighting:

Halogen headlight, LED taillight/brake light, amber incandescent turn signals.

Frame Construction:

Security System:

Optional Harley-Davidson Smart Security System with proximity-based fob.

💡 Technology Features

Instrumentation:

Analog speedometer, tachometer (on some models), gear indicator, fuel gauge, odometer, trip meters, and indicator lights. Diagnostics are accessed via the speedometer display.

ABS:

Optional ABS available on select models. Manual covers ABS system diagnostics and service.

Diagnostic Tools:

The manual is essential for using Harley-Davidson's proprietary diagnostic tools (e.g., Digital Technician) for advanced troubleshooting.

🔧 Maintenance

First Service:

1000 miles or 12 months, whichever comes first. Includes engine oil and filter change, inspection of primary drive, transmission, brakes, controls, and drive belt.

Subsequent Service:

Every 5000 miles or 12 months thereafter. Includes similar inspections and service as the first service, plus checks for drive belt tension, brake fluid condition, and wheel bearing play.

Engine Oil:

Harley-Davidson SYN3 (Synthetic) SAE 20W-50 or equivalent API CI-4, JASO MA-spec. Capacity: 3.5 US qt. (3.3 L) with filter.

Primary Chaincase Oil:

Harley-Davidson Formula + Transmission/Primary Chaincase Lubricant or equivalent API GL-5, SAE 75W-90 synthetic gear lubricant. Capacity: 3.0 US qt. (2.8 L).

Brake Fluid:

DOT 4 brake fluid.

Fork Oil:

Harley-Davidson Factory recommended fork oil (e.g., Harley-Davidson Suspension Oil Type E or equivalent SAE 15W). Capacity varies by model (e.g., 12.2 US fl oz / 360 ml per fork leg for Street Bob).

Engine Vibration:

While the Dyna uses rubber mounting, some vibration is inherent to the V-twin design. The manual provides guidance on inspecting and maintaining engine mounts.

Cam Chain Tensioner:

Early Twin Cam engines used spring-loaded cam chain tensioners that could wear over time. Later models, including the 2013 Twin Cam 103, typically use hydraulic tensioners, which are more robust. The manual details inspection and replacement procedures.

Clutch Adjustment:

Regular inspection and adjustment of the clutch cable and free play are crucial for smooth operation and preventing premature wear.

Drive Belt Tension:

Proper drive belt tension is critical to prevent premature wear of the belt and bearings. The manual outlines the correct tension measurement and adjustment procedure.
