Yeah, I think the speeds have been greatly over exaggerated. The bike can clearly be heard to be shifting or briefly backing out of the throttle before it gets to the bridge, so nowhere near its top end.
Also, 330 km/h is MotoGP speed at the fastest point on their calendar; the end of Mugello's main straight. So that would then have to be a heavily modified superbike or a standard ZX-14R with its limiter removed.
My guess is the cars were in the 200 - 240 range with the bike a little faster and still building speed.
Still stupid fast though when you consider that fact that these cars are only crash tested at a max of 65 km/h. Any accident at 100+ would tear a car to pieces. An accident at 290/300 would be an explosion.
MotoGP bikes are not setup for top end speed, all depending on the track and the max length of the longest straight. Those bikes can easily go over 400km/h with the right setup. Not sure where you got that 340Km/h as that is not true at all
Valentino Rossi,
1996, Aprilia and the top speed in the history of MotoGP is
356.4 km/h (
221.5 mph)
Friend's bike tops out at 376kmph. (not standard obviously)
My family sedan gets to 260km/h in no time, and it does not feel fast at all, those 2 cars were moving very fast, one can never judge speed my looking at a video clip, it always looks like they are driving slower that they actually are.
