*Most* of the Harley crowd has no interest in power or speed. Their main focus is on personalizing their bikes to fit their tastes, including the sound. That said, there are some that are obcessed with trying to tweak out more power. Those are the guys that make me scratch my head.
I have a buddy that spent $38K on a Screaming Eagle Ultra Classic Electra Glide. He used to spend every waking moment yapping about how fast it was, blah blah blah. Another guy mentioned my R3T to him and he was actually stupid enough to come back with "I don't know, I think my Ultra would give it a run for its money". The next time we were out together, we ended up on a straight stretch of highway. I RARELY race my bikes or even ride them fast, for that matter. But, I made an exception this time and I looked over at him and gave him the nod.
He downshifted and took off. I hardley even rolled into the throttle. I rode beside him for about 10 seconds (one handed). He looked over and I grinned at him, rolled full throttle and waved goodbye. He was a small spot in my mirror soon after. He's never said a word about his bike being fast again, anytime I'm around.
