Replacement parts, Chrome Power Pack cover (OEM 69139-54, 69140-54)
The trumpet horn was standard on 1954-1964 Panhead Big Twins with their 6 Volt generator and disappeared from the 1965 models when The Factory went to 12 Volt. Complete kits have a chrome horn and chrome Power Pack cover and include all required hardware. Great for those who prefer the classic looks on later models.
