Positioning:
The Harley-Davidson Softail models of the late 1990s represented a significant evolution in the cruiser market, offering iconic styling with modern (for the era) engineering. These motorcycles appealed to riders seeking classic looks, a comfortable ride, and the distinctive Harley-Davidson V-twin experience.
Competitors:
Competitors during this period included other American V-twin manufacturers and Japanese manufacturers offering cruiser-style motorcycles with V-twin engines, such as Indian, some Honda Shadow models, Yamaha Virago models, and Kawasaki Vulcan models.
Design Philosophy:
Softail models are characterized by their hidden rear suspension, creating a hardtail appearance while providing a more comfortable ride. The Evo Big Twin engine delivered characteristic torque and a rumble that defined the Harley-Davidson sound.

Displacement:
Typically 1340cc (81.9 cubic inches) for this era's Big Twin models.
Bore X Stroke:
Approximately 3.496 in. x 4.25 in. (88.8 mm x 108 mm)
Compression Ratio:
Typically around 8.8:1 to 9.1:1, depending on specific model and tuning.
Horsepower:
Estimated 55-65 HP at the crankshaft (actual figures varied by model and year).
Torque:
Estimated 65-75 ft-lbs at the crankshaft (actual figures varied by model and year).
Carburetor Type:
Keihin CV (Constant Velocity) carburetor (e.g., CV40) is common. Some models may have been available with early fuel injection systems.
Fuel Type:
Unleaded gasoline, 90+ octane recommended.
Oil Capacity:
Approximately 3 US quarts (2.8 liters) for the engine/transmission/primary drive combined, with a separate oil tank.
Oil Type:
Harley-Davidson recommends specific V-twin motorcycle oils, often a multi-viscosity with a high zinc content (ZDDP). Common recommendations include SAE 20W-50.
Transmission Type:
5-speed constant mesh, manual transmission
Clutch Type:
Wet, multi-plate clutch operated by cable.
Primary Drive:
Chain drive (e.g., 1.469" pitch duplex chain) from engine crankshaft to clutch basket.
Final Drive:
Belt drive (e.g., 40mm wide belt) from transmission pulley to rear wheel sprocket.
Transmission Oil Type:
Harley-Davidson recommends specific transmission lubricants, typically SAE 80W-90 gear oil or dedicated Harley-Davidson transmission oil.
Oil Change Interval:
Typically every 2,500-5,000 miles (4,000-8,000 km) or annually, whichever comes first, depending on riding conditions and oil type used.
Primary Drive Lube Interval:
Check and top off as needed, typically with each oil change, using specified primary chain lubricant.
Transmission Oil Change Interval:
Typically every 5,000-10,000 miles (8,000-16,000 km) or annually.
Belt Drive Inspection:
Inspect belt tension and condition regularly (e.g., every 2,500 miles) and adjust as per manual specifications.
Brake Fluid Type:
DOT 4 hydraulic brake fluid is typically specified.
Common Wear Items:
Clutch wear, belt drive wear, wheel bearings, brake pad wear, carburetor tuning sensitivity, potential oil leaks from seals (e.g., primary drive seal, transmission seal).
Electrical Gremlins:
Older wiring harnesses can develop issues; consult wiring diagrams for diagnosis.
Evo Engine Characteristics:
The Evolution engine is known for its durability and character, but requires regular maintenance to keep it running smoothly.
Brand Legacy:
Harley-Davidson, founded in 1903, is one of the oldest motorcycle manufacturers globally, renowned for its V-twin engines, distinctive styling, and the 'Harley-Davidson lifestyle'.
Softail Introduction:
The Softail line was introduced in 1984, designed by Bill Davis and later refined by Harley-Davidson. Its defining feature is the hidden rear suspension, mimicking the rigid look of early hardtail frames while providing rider comfort.
Manufacturing Location:
These models were primarily manufactured in the United States, at Harley-Davidson's York, Pennsylvania, and Milwaukee, Wisconsin, assembly plants.
