The Denali SoundBomb horn from R and G Racing is eight times louder than a standard motorcycle horn producing 120 decibels of sound. The SoundBomb is designed for those who want to be heard but still want to maintain a stylish look. It has a compact design and blacked out housing meaning the SoundBomb will practically be invisible once fitted. Its unique design features a rugged moulded clamp that mechanically mates the compressor to the acoustic unit making it almost indestructible even in high vibration applications. It is also compatible with all CANbus electrical systems.Please note - Certain newer BMWs have a single horn connector and require an additional connector.Currently this horn is not compatible with KTM 1190 & 1290 Motorcycles.
