I'm on an obsessive quest to get a Harley, somewhat typical for guys above 50. Its atypical how I became interested. Their sound is more interesting than music.
Beginning in the 1990's I began playing bass, I was good enough exactly a year later to be invited to a studio to record. Later I switched to Chapman Stick, upright acoustic bass, Stratocaster, and finally a fretless MusicMan Stingray. I finally sold the Stingray in 2009, simply because I didn't have time or space to practice. Then in 2011 I got a Fender acoustic guitar, loved it and excelled at a certain style of playing. (see most instruments here)
What happens next is, I feel, unusual: I sold the Fender. I had decided the idea of practice, and more than that...playing...was no longer what I was interested in. I moved on to creating music using Moog analog synth software, no use of a keyboard, just configure and let it run.
At some point in this Moog playing phase I discovered the northbound express lanes on Interstate 5 in the center of downtown Seattle. These are special separate lanes one level lower than the normal northbound lanes. They are subterranean, with concrete and metal roof, and
large metal and concrete structural support all around. In some parts the city is visible, and eventually it becomes a bridge over the ship canal with the main interstate as a roof.
I decided the sights and noise of that road environment was far more of what I wanted out of audio entertainment than any form of music playing. I instantly made the connection that being on a motorcycle would soak up more of the visual and audio environment. The next logical step is only intuitive to a musician or sound engineer: the walls and shapes of that environment only come alive via reverberation with the sound of a motor, especially a loud and interesting sounding motor.
Enter Harley-Davidson into this musical discussion. 
Their motor design is archaic, inefficient, and less powerful than most modern designs. They are also beautiful sounding. Their sound is music, and most add loud pipes so the musicality is even louder, much like the principal that an electric guitar playing through a 100 watt amp is more interesting than an acoustic.
I am done with a personality coming through their instrument, their story coming through the chord changes of a song. I am done with being entertained by a person, and done with being a person who wants to entertain, who wants attention. I want sound, interesting unnatural sound. I want something bigger than a personality, than a story. I want to hear reverb coming off a giant bigger than myself, bigger than any rock star, bigger than any song.
I want to hear the loudest pipes possible, roaring to the point of noise pollution, bouncing off big objects in the night. I want to be changed internally with the nuances of this pollution, into something new: a man that is pollution, Interstate and industrialized desert.
