As a car-person, gear head / petrol head, etc., this has always been somewhat baffling to me. I've always been in it for the speed, the exciting sensation of your body moving through space. Lots of things end up being kind of cool by association: fat tires, wings, loud exhaust, a lopey idle. But to me they were only interesting because of what they implied, something that can go fast. Some people add those things without being able to go fast, which I've always found distasteful, a thing frequently derided as "all show and no go". It took me a while to accept that some people really are in it for the noise. I can't really knock it, I'm getting a sensory experience that I enjoy but can't quite explain, and I suppose they are too. But keep it away from my house. ;-)

Once I was riding my motorcycle to work, and another guy rode passed me on his motorcycle. His exhaust was so loud it gave me a headache almost instantly. I can't imagine how much it must hurt to actually ride the thing.
