Transmission Fluid Type:
Harley-Davidson 3-speed transmission oil (older spec) or dedicated 4-speed transmission oil
Transmission Fluid Capacity:
Approx. 1 US Quart
Wheelbase:
Approx. 63.5 inches (for Wide Glide)
Rake Trail:
Significant rake angle for the Wide Glide front end, typically around 32 degrees rake, with corresponding trail figure for stability.
Dry Weight:
Approx. 580-600 lbs (varies by accessory)
Gross Vehicle Weight Rating:
Approximately 950-1000 lbs
Safety Ratings:
Motorcycle safety is largely rider-dependent; no formal crash ratings like cars.

Lighting:
Headlight, taillight, brake light, turn signals
Frame Design:
Robust steel frame designed for stability and handling
Oil Change Interval:
Typically every 2,000-3,000 miles or as per manual recommendations for the Shovelhead engine.
Primary Chain Tensioner Check:
Frequent checks recommended, especially after initial break-in or rebuilds, as these can wear.
Spark Plug Replacement:
Generally every 5,000-10,000 miles, dependent on plug type and condition.
Engine Oil Specification:
See engine_specs.lubrication.oil_type for general guidance; consult manual for exact Harley-Davidson recommended viscosity and API service classification.
Transmission Oil Specification:
See transmission.features.transmission_fluid_type for general guidance.
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid (check specific caliper/master cylinder recommendations)
Shovelhead Common Problems:
Oil leaks (pushrod tubes, base gaskets), primary chain tensioner wear, kickstart mechanism issues, ignition timing sensitivity, carburetor tuning quirks.
Wide Glide Specific Issues:
Fork seal leaks, potential for frame stress in heavily modified or abused examples.
Foundation:
Harley-Davidson Motor Company, founded in 1903, is an iconic American motorcycle manufacturer.
Shovelhead Era:
The Shovelhead engine was produced from 1966 to 1983/1984, evolving from Panhead designs. The FXWG model specifically debuted in 1980, establishing the Wide Glide aesthetic.
