The 1987 Harley-Davidson Sportster 1100 is equipped with a dual encapsulated ignition coil.

This means that it has one housing containing two coils.

The ignition system operates using a dual-fire spark mechanism, which fires both spark plugs simultaneously regardless of which cylinder is in the compression stroke.

 This design simplifies the ignition system while providing effective spark delivery to both cylinders.
