How do you work out your speed from a rev counter ?

How do you work out your speed from a rev counter ?

If you know your tyre size, and your gearbox, with the Avantone's fantastic app you can see your rpm and the speed to this rpm.

I use a garmin forerunner which is GPS running 17/46 6000 rpm = 59mph 7000 = 70mph 8200= 82mph
82mph on a main strem road frightening bike all over the road been told its tyres (racemans) my bike will rev to just over 10000 rpm so you can work it out
I now think its not how fast we go but how fast we can get there

Also ensure your clutch is not slipping, because 10,000 won't = 100 mph if it is.

10,000 rpm thats why i had to fit new clutch (RT 7 plate ) only thing is this could be boarder line too

But will it rev to 10k in 4th on the road? Mine'll rev to 9k on a dyno with the same gearing and a Devtour pipe, but it won't do 90mph on the road.
BTW what oil you running with that clutch?

whitelighting...........stop it carl !........ no more RPM...... we all know shes quick off the mark with a pint pot like you steering her

Soulsurfer, do you have a link to the online manual for the clutch? I need to know what metal the crownwheel is made from?

Soulsurfer it went to 10,500 on the road I thought it was going to blow up scared me to death but to be real more than 90mph on road who wants it
I now no not me thank you
