I sure wish this had been available when I owned a Sportster. Harley-Davidson announced today that a new Boom! audio system is now available for the 2004-later XL Sportster, 2010-later Dyna Wide Glide, 2000-later Softail, and 1999-later Road King models.
From the H-D press release:
The new Boom! Audio Cruiser Amp and Speaker Kit (P/N 76262-08 Chrome, 76320-08 Black; $399.95) from Harley-Davidson Genuine Motor Accessories provides amplified music through two 3.5-inch speakers. The individual speaker pods clamp to either a 1-inch or 1.25-inch handlebar and can be adjusted to direct the sound toward the rider. The waterproof speaker elements are protected behind black-and-chrome grilles that are finished with a center-mounted Bar & Shield medallion. The compact two-channel stereo amplifier mounts on the frame downtubes. A stereo auxiliary input connects to most portable audio players, some of which can be easily housed in a convenient BOOM! Audio Tank Pouch (sold separately). The integrated hand control features volume up/down buttons and a backlit on/off button, and is designed for easy operation with the rider’s right thumb, even while wearing gloves.
It’s now available from Harley-Davidson dealers.
