Hi Kevin,

The link doesn't seem to work so I couldn't check for sure, but this
appears to be a regular brushed motor.

Assuming that it is a brushed motor, 12V will not damage it. The
no-load speed will be lower, as well as the slope of the torque-speed
curve will be steeper (i.e., the motor will run slower and have less
maximum torque). The efficiency should not be greatly affected.
