Top Speed?

[R-III-R Turbo]

Wurzel we at Rocket Performance HQ need you to find out the exact RPM at exactly 80mph / 129kph please

That‘s my guess. Head is a bit vibrating at that speed and in the chron2 mode the rev displaying is still a bit small

I can't stand the Chrono theme.. I have tried it for two hours on my Scrambler 1200 and 30 minutes on Rocket Now i can safely say it's NOT for me!

I've had these calculations done since November 2019, and have been waiting for someone to give us the real top speeds per gear etc!

Thank you my friend. By your quite accurate and reliable reading, 3000rpm in 6th will be about 75.2 mph (121kph).
80mph (129kph) would be about 3200rpm in 6th. Speed at 7000rpm in 6th about 176mph (283kph).

So it appears my maths were not bad

Now:
129 in sixth gear speedo 2950
129 gps (speedo 134) 3000-3050

Will they really go that fast? Even if not limited I doubt they will attain that speed.

 

[Joesmoe]

The amount of drag increases at least with the square of the velocity, with drag exceeding other factors past about 40 mph.

So a little more power makes available less speed.

Almost all geared vehicles are power limited.

And measurement instruments are almost always most accurate in mid-range, and why a properly matched speedometer will go far higher than the vehicle is designed.

Little bit of a contradiction there, must be a small error in the tacho?

Theoretical top speed, assuming speed limiter was raised, and either had the power to overcome wind, rolling resistance etc or was on a dyno
