Why don't you go find out and report back.

This is a typical ride with JCZ.
Following JC is always a fun ride.
Not 120 but it did stay on a 100 for many many miles.

When I'm going 120, I'm usually looking at my iPad mounted on the left handlebar, so I can make sure I get those 80 kPa, 4000+ RPM cells all filled in GREEN on the DataMaster histogram!!! 

Or at the radio to get the iPod to play "Highway To Hell"...

Double your 60 mph / rpm

[Cvostu]

That's sounds like the best idea of em all.  And maybe you won't kill yourself along the way.

Who rides 60, either, though.

[Cvostu]

Then you can take it back to 90 after you do the math.

And JC is trying to fight a speeding ticket?

Must have an inaccurate speedo or tach, since 4200 rpm should equal 114 mph according to the calculator.  I think you should file a complaint with H-D.

My speedo is off by 4 mph versus the GPS at 110 mph, so a 6 mph error at an even higher indicated speed doesn't seem outside the realm of possibility.

Trust me, I did my own calculations as well as plugging the info into that calculator Terry posted a link to.  4200 rpm with stock gearing and tire is 114 mph, just like that calculator says.  Harley speedometer's are pretty optimistic when you get into the triple digit area.

HD speedometers are "happy", as are a lot of auto speedometers.  Mine read 3 mph faster than I was going at "normal" speeds (60-80mph), and may have been worse at triple digit speeds, I don't know.  I calibrated mine to within .5 mph (close enough for government work) with the TTS.  If in doubt, look at the GPS speed...it's accurate if it's picking up more than two satellites.

My bike has seen 120mph, but only for a very brief period of time...things happen very quickly at 120mph so my eyes are pointed directly in front of me.

checked mine again it was 4200 rpm at  120
