When I left work tonight the sun was low in the sky, the winds were picking up and traffic was light. I decided to make the trip home a brief one. I leaned into the curve of the freeway on-ramp and opened up the throttle. I flew north at speeds between 80 and 100 MPH for about 20 miles. Whether at 80 or 98 MPH, the bike glided along effortlessly - much like a wing-suited skydiver silently screaming down the slope of some steep Swiss mountain.
Finally the flashing red temperature light came on, but I only had to slow to 75 MPH for a mile or so before it disappeared.
This thing is just amazing.

Dear Mr Oobflyer,

Thank you for your honesty, the citation is in the post.

Yours Sincerely,

What was the weather (temperature and humidity) on your ride?

LOL-  did I say miles per hour? I meant kilometers per hour :-)

What was the weather

The  weather was clear and dry, but the temps were dropping from the 70s into the 60s while the sun was setting…

That kind of pleasure is worth the risk of a ticket, great stuff!

The first time I saw the light flashing I only had 25 miles on the bike.  My first thought was "Great, I already broke it."  After consulting the manual, I realized nothing was wrong and it was merely informing me that power MAY be reduced if I maintain these speeds. This is what the manual says about the temp light:

Zero Motorcycles has developed the most advanced
passively air-cooled electric powertrain for your Zero
motorcycle, delivering an unsurpassed level of simplicity,
power/energy density, low weight and ease of
maintenance. However, this passively air-cooled
powertrain cannot be operated indefinitely at high power /
high rpm without reaching its thermal limitations. Hence,
your Zero motorcycle has a sophisticated thermal
management strategy to ensure the long term
performance and durability of its powertrain.
The red temperature indicator light (A) on your Zero
motorcycle’s lower dash has two informational stages.
ï‚· Stage 1, is presented by flashing this indicator and
advises you that the bike is about to enter its thermal
strategy. To avoid encountering an enforced power
reduction, you can choose to slow down a bit until the
indicator stops flashing.
ï‚· Stage 2, if temperature continues to build, the indicator
light will go solid, letting you know that the thermal
strategy is now being applied and that your
motorcycle’s power will be reduced accordingly. If you
encounter the strategy while trying to maintain a high
vehicle speed, the effect of the strategy will be that your
motorcycle will be gradually slowed down to the point
that the top speed of the bike is “sustainable,” from a
thermal standpoint. If you encounter the strategy due to
a different sustained high power event, such as
continued powering through a low traction surface,
power will simply be reduced to ensure the continued
safe operation of your powertrain.
Please note that the lighting of this temperature indicator
does not indicate that there’s anything malfunctioning with
your Zero motorcycle; it is simply letting you know that the
thermal strategy is working. If you do not moderate your
speed/power, the bike’s system will reduce your
speed/power until your Zero can maintain its maximum
allowable thermal state; but no harm whatsoever will result
from this, since this is exactly how the strategy is meant to
function.

I've since come to ignore the light pretty much entirely, since the owner's manual tells me the bike will do whatever it needs to do to protect itself.  I've only had it cut power on me due to temperature one time.  It slowed me down to below 90 and it didn't occur until the temperature had exceeded 265°F.

Well, you ride faster than I do Tater.  The highest temperature that I have ever seen on my 2014 S is 165 degrees.
