Approximately 4.5-5.0 US quarts (4.3-4.7 liters) with filter change. Consult manual for exact spec.
Engine Oil Type:
Harley-Davidson V-Twin 20W-50 SYN3 (Synthetic) or equivalent API CI-4 or higher rated motorcycle oil.
Coolant Type:
Ethylene glycol-based antifreeze, typically a 50/50 mix with distilled water. Harley-Davidson specific coolant recommended.
Instrument Cluster:
Analog tachometer with a digital speedometer display, odometer, trip meters, fuel level, and indicator lights. Some models may have additional digital readouts.
ABS:
Anti-lock Braking System (ABS) was an optional feature, particularly on later model years within this range.
Diagnostic Ports:
Features diagnostic connectors for accessing engine control module (ECM) data using Harley-Davidson specific diagnostic tools (e.g., EST - Electronic Service Tool).
ECM:
Engine Control Module (ECM) manages fuel injection, ignition timing, and other engine parameters based on sensor inputs.

V Rod Genesis:
The V-Rod platform (VRSC) was a significant departure for Harley-Davidson, launched in 2001 for the 2002 model year. It was the result of a collaboration with Porsche Engineering Services to develop a liquid-cooled, high-performance engine that differed from their traditional air-cooled designs.
Model Timeline Within Range:
The VRSCA (V-Rod) was the inaugural model. Subsequent years saw variations like VRSCAW (longer wheelbase), VRSCB, VRSCX, and the more sport-oriented VRSCR (Street Rod).
Manufacturing Location:
United States (primarily York, Pennsylvania and Milwaukee, Wisconsin facilities)
Production Years For Vrsaca:
2002-2007 (The VRSCA designation itself evolved, with the VRSCAW becoming more prominent later in the platform's life).
