ABS:
Anti-lock Braking System (ABS) was an optional feature for some 2002 Softail models.
Diagnostics Port:
Factory diagnostic capabilities typically rely on Harley-Davidson's proprietary diagnostic tools (e.g., Digital Technician).
Initial Service:
Recommended at 1,000 miles (1,600 km) or 3 months, whichever comes first.
Subsequent Service:
Typically every 5,000 miles (8,000 km) or 12 months, whichever comes first.

Cam Chain Tensioner Wear:
Early Twin Cam engines (though Softail 2002 is primarily Evo, some later models might have had early Twin Cams, but the description points to Evo-era) had issues with cam chain tensioner wear, requiring upgrade to hydraulic tensioners. *Correction: 2002 Softail models are primarily Evolution (Evo) Big Twin, not Twin Cam. Evo models do not typically suffer from cam chain tensioner wear in the same way.*
Carburetor Tuning:
Keihin CV carburetors can require periodic adjustment or cleaning for optimal performance.
