Upgrade your motorcycle with the Kleinn direct drive dual air horn system, engineered specifically for riders who demand premium quality and a clean, vehicle-specific fitment. This premium heavy-duty package is designed to completely replace the weak factory horn assembly on 1979 to 2020 Harley Davidson motorcycles equipped with the classic cowbell style horn cover. By cleverly reusing the original factory horn cover to house the new components, this system ensures a seamless, hidden layout that maintains a clean and better than factory appearance on your bike. This high-performance acoustic package features dual black air horns driven by a powerful, compact direct-drive air compressor that fits neatly into place without the need for an external air tank. Engineered to deliver an instant, attention-grabbing response, the system rewards you with a commanding 132 decibel blast to ensure you are always heard on the open road. The kit includes all the necessary wiring, high-grade hardware, and mounting components for a straightforward installation using common hand tools. Built to endure the toughest riding environments and vibrations, this complete horn kit provides the ideal balance of discreet original equipment manufacturer styling and the legendary, professional-grade performance that serious riders count on.
