“If you want to tell me that going fast is all about torque and tractors doing wheelies I really would suggest that you read up a bit more on the subject.”

Clearly not my words, don’t even suggest such. What’s your point. What, are you going to school me now. I have a college education too, lol. In fact, I’m an accomplished jet engine designer among other things. I never said the Sportster was the fastest bike in the world now did I. The Sportster’s torque curve is significantly higher than horsepower approaching inversely proportional until you hit around 5800rpm. There is a reason why they have ruled the flat track for decades. http://www.baggersmag.com/horsepower-vs-torque-horsepower-rules-torque-king

You said it "jerked a knot in your *ass," which it clearly doesn't. You also denigrated the posters on the thread in your first post, calling them quote-unquote experts and half of them being unable to handle your machine. Your machine LOL That Harley is a slow ride and you can't deny it. You started out with a typical Harley rider's huff and puff and then kept putting your foot in your mouth with your going on about torque and telling me to read up on the subject. As an actual engineer I would have expected you to have a better understanding of the subject. Still, I have to admit, you do seem to know more than most Harley drivers (note I didn't say riders) which go on and on about how fast their machines are until they actually get out on the road. I think we've both had enough. Later dude.

At the risk of stirring the pot some more.......
The power delivery of the uneven firing order has something to do with this also. Kind of like a mechanical traction control. The pauses allow the tire to recover traction. An inline four with the same output could not put it on the ground as well. I heard this straight from Roger Reiman so I’m inclined to believe it.
