I have had my G2.5 1200 up to an
indicated 249 km/hr (~154 MPH) just cuz I could. It was on a very slight downhill with no wind of any kind. Unfortunately I was too busy watching the speedo with one eye and the road with the other to take note of the revs.
That is, hands down, the fastest I've ever gone in/on anything with wheels and no wings.
#17 didn't feel like she was straining or anything....but the rev limiter was doing its thing at the end of the run so I must have been hitting 11K RPM.
I may never do that again....but it's nice to know that could if I wanted to.
Now I've had a somewhat pale example of what the Moto GP and WSB guys experience.....but they do it every lap.
