Just doing some research.  Can anyone report reasonably accurate rpms for something around 70 mph?  (or 110 kph, etc)  Thanks!!  I have web searched and youtubed without any success so far.  I found a web pdf with the primary/secondary/six-gear ratios, and tried to back-calculate but computed 4868 rpms for 72 mph which seems high.  I could only estimate tire circumference for the rear 180/55/17.  Oh, and hai there, Cruizin!
 
primary 77/40 1.925
secondary 16/43 2.688 (sprockets)
1st gear 37/13 2.846
2nd gear 34/16 2.125
3rd gear 31/19 1.632
4th gear 26/20 1.300
5th gear 24/22 1.091
6th gear 27/28 0.964
 
72 mph * 5280 ft/mi * 12 in/ft * 1/60 min/hr * 1/77.9 rev/in * (1.925 * 2.688 * 0.964) = 4868.51 rpms ...

I think 4868 rpm at 72 mph sounds about right. I am doing that from memory though. It is too late for me to go out and verify it tonight. Sorry.

D'oh, duh I can punch those exact numbered into gearingcommander, yup it agrees. I'll try to upload it to their website using the form.

There you go! :D
 
Crud, 4800 rpms only seems high because I messed up my kph vs mph in GearingCommander on most of the bikes in my chart, >_<

If you are asking for actual readout of tach at 70mph in 6th gear, my instruments indicate 5,000RPM @ 70MPH.  Speedometer is accurate when compared to my Garmin.
