Horsepower:
Approx. 60-65 HP (peak, estimate for this engine configuration)
Torque:
Approx. 70-75 lb-ft (peak, estimate for this engine configuration)
Torque Curve Characteristics:
Emphasis on low-end and mid-range torque, typical for Harley-Davidson V-twins, for strong cruising performance.
Fuel Delivery:
Carbureted (Keihin CV 40 mm)
Fuel Type:
Unleaded Gasoline, 91-95 Octane (RON+MON)/2
Oil Capacity:
3.0 US quarts (2.8 L) (with filter change)
Oil Type Spec:
Harley-Davidson SAE 20W-50 (or equivalent API CG-4 or higher)
First Service:
1,000 miles (1,600 km) or 6 months, whichever comes first.
Subsequent Service:
Every 5,000 miles (8,000 km) or 12 months thereafter for routine checks, oil/filter changes, and component inspections.
Engine Oil:
Harley-Davidson SAE 20W-50, Harley-Davidson Genuine Motor Oil.
Transmission Oil:
Harley-Davidson Formula + or SAE 50 Motorcycle Transmission Oil.
Primary Chain Case Oil:
Harley-Davidson Formula + or SAE 50 Motorcycle Transmission Oil (shared with transmission).
Brake Fluid:

Fork Oil Spec:
Specific weight of fork oil required for front suspension (e.g., Harley-Davidson Type HD 10W, or equivalent).
Potential Issues:
Cam chain tensioner wear (especially earlier models), carburetor tuning sensitivity, potential for oil leaks from seals, electrical connector corrosion (common in humid environments).
Maintenance Focus:
Regular oil changes, checking primary chain tension, inspecting cam chain tensioners (often upgraded to hydraulic units in aftermarket), keeping electrical connections clean and dielectric greased.
Brand Origin:
Harley-Davidson Motor Company, founded in 1903 in Milwaukee, Wisconsin, USA. A long-standing manufacturer of V-twin motorcycles.
Softail Lineage:
The Softail platform, introduced in 1984, is known for its characteristic 'hardtail' appearance achieved by hiding the rear shock absorbers beneath the transmission and swingarm, providing a smoother ride than traditional rigid frames.
Manufacturing Location:
United States (primarily York, Pennsylvania and Milwaukee, Wisconsin plants).
