This electronic regulator for 12 Volt Big Twin models from 1965 thru 1969 and Sportsters from 1965 thru 1982 bolts straight onto the generator end cover. It is a solid state ceramic hybrid construction that has already proven to be far more reliable than the stock mechanical regulator. Also cleans up the looks of your bike as it releases you from the separate, in sight frame mounted regulator. Black finish with highlighted cooling fins.
