Transmission Type:
5-speed constant mesh, sequential manual.
Primary Drive:
Double-row chain (45-tooth front sprocket, 32-tooth rear sprocket) or belt drive.
Final Drive:
Belt drive (e.g., 29-tooth pulley to 65-tooth rear sprocket).
Clutch Type:
Wet, multi-plate, diaphragm spring.
Transmission Fluid Spec:
Harley-Davidson transmission lubricant or equivalent API GL-4 gear oil.
Wheelbase:
Varies by Softail model (e.g., 64.5 inches for Fat Boy).
