I can tell you there is no finer joy in this life than the potato potato potato sound a Harley makes as you pull a way from a stop. I soothes the soul. It feels good. The only thing better than that is the gentle vibrations shaking your bottom like the rubes would get an vibrating chair for. And this is part of the therapeutic experience. Not too quick, no too slow, with a low redline, plenty of torque, and wide spaced gears, the harley is easy, comfortable as a big vibrating couch rolling down the road, lay back, easy riding.
