General Operation
4.5
Temperature Indicator
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 the lower dash
has two informational stages.

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.

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.
