2015 Harley-Davidson® FLHXS - Street Glide® SpecialWhen it comes to stripped-down bagger style, highway comfort, modern technology and an unruly attitude, this is a state of the art motorcycle.Boom!™ Box 6.5GT RadioThe Boom!™ Box 6.5GT Radio puts out 75 watts per channel at 1% distortion and features a factory-tuned, optimized equalizer that pumps out more power and can be played louder while maintaining the clarity of your sound. And the speed tuning system delivers more than just volume changes at different speeds. It changes the level of bass and treble to dial in the best sound, whether you’re running at a stately pace down the strip or going hell for leather down an open stretch of road. How do you like the sound of a Harley® motorcycle?Project RUSHMORE - ComfortWe dialed in the comfort of our machines the hard way: over thousands of miles in all kinds of riding conditions on every kind of street, road and highway ever laid down in pavement. Experienced riders putting in long hours in the saddle and giving us feedback on every aspect that contributes to comfort on the road. Airflow, heat management, seat textures, legroom and hand controls all went under the hard microscope of the road and got tested and re-tested by real riders and worked and re-worked by us until we were satisfied we had built the most comfortable machines on the road. We all want to go farther, and when you're more comfortable in the saddle, you can.
