I think it is the sound of the wheelie bars scraping the track.

I'm sure my slicks do it to, but you can't hear them over the exhuast and engine noise.

I'm sorry to be such a nerd about a stupid sound, but it's just fascinating that a tire can make that noise.

I hear 2 distinct sounds, one sounds like an RC car, the other like ripping cloth.

The first would be the motor, the latter the tire. And it is an interesting sound at that.

BTW, slightly off-topic, but is anyone else tired of hearing about "silent" electric cars? All the ones I've seen make as much or more noise than some quiet gas engines, and I rather like a car that lets people know when I'm moving. As in a warning to other drivers and pedestrians, yes, I really am accelerating at a rate of 32fps^2

0-100 KILOMETERS PER HOUR fellas... they're in Europe.... I think Bill said it takes about 2 seconds, not 1.

remember that a typical 1.0litre supersport bike (about $12,000) goes 180mph and goes 0-60mph in about 2.5 seconds. and gets mid to high 20's MPG.

There saying 0.8sec 0-60mph.

Whats the 1/4 mile like in a superbike?

Not if you take the muffler off.
But, I don't understand the argument.
Even modern ICE vehicles with good mufflers are very difficult to hear from behind when you're biking.

Motorcycles need to have some sound report for safety reasons because they're more difficult for other motorists to see.
