Maintaining Top Speed...

[-Taurus-]

So, this is a detail i'm curious to know about for a little while now.

In Gran Turismo, the one i remember best is the first one, and recently with Tourist Trophy is that when the cars or the bikes reach their top speed, they are incapable of sustaining that speed.

Better explanation, take for example a bike in Tourist Trophy that has a top speed of 140 km/h. When it reaches that speed, the bike starts to hick-up between 135 and 140 km/h, always going up-down-up-down between those speeds.

is this realist, does real cars or bikes behave like this in real life at all, or do they sustain their top speed without hick-up?

If you hit the rev-limiter in top gear the engine cuts for a second or two then cuts back in (once the revs have droppped a bit), so yes it does happen in real life (so I'm told )

Adjust the gear ratios so it doesn't hit the redline in top gear.
