6 Volt Coils, 500,650 63-65 Works with Boyer for Triumph, Norton, BSA
"Lucas Copy" ignition coils for Triumph 500, 650 AND 750 motorcycles from 1963-1966. They can be used on later unit models if you are converting to a 12 volt Boyer electronic ignition (the coils produce a stronger spark because of the ohm resistance). We use these coils on the builds, they are virtually bulletproof. We highly recommend you use copper core wires with your new coils, especially if you are running modern electronic ignition systems. We also recommend using the proper spark plugs for your motorcycle.
