Headlight, tail light, brake light, turn signals for visibility.
System:
Basic instrumentation typically includes speedometer, odometer, trip meter, tachometer (on some models), and indicator lights. No advanced infotainment systems as found on modern vehicles.
Features:
No electronic driver-assistance systems (e.g., ABS was optional and not widespread on 2003 models). Focus is on mechanical systems and rider control.
Features:
No integrated connectivity features (e.g., Bluetooth, smartphone integration).
First Service:
Typically around 1,000 miles (1600 km) for initial engine break-in service (oil change, primary drive adjustment, chain check, general inspection).
Subsequent Service:
Every 5,000 miles (8,000 km) or annually, whichever comes first, for major services including engine oil, transmission oil, and primary chaincase lubricant changes.
Spark Plugs:
Recommended replacement every 10,000 - 15,000 miles (16,000 - 24,000 km), or as specified in the manual.

Primary Chaincase Oil:
Harley-Davidson primary chaincase lubricant (e.g., Formula+ or equivalent). Capacity: Approx. 1.2 US quarts (1.1 Liters).
Brake Fluid:
DOT 4 hydraulic brake fluid (for models without ABS). Check manual for specific type and fluid reservoir locations.
Twin Cam 88:
Early Twin Cam 88 engines (prior to the 2007 upgrade to the TC96) could be prone to cam chain tensioner wear, oil leaks, and potential primary bearing issues if not maintained properly. The manual will detail checks and procedures for these.
Carburetor:
Keihin CV carburetors can require periodic tuning adjustments for optimal performance and can be susceptible to diaphragm issues over time.
Belt Drive:
The belt drive requires proper tensioning and regular inspection for wear or damage, which the manual will cover.
Legacy:
Harley-Davidson, founded in 1903, has a long and storied history in American motorcycling, known for its V-twin engines and cruiser styling.
