here is the link to the actual source of the motors, BaneBots Buys them from here, and according to this spec sheet
http://www.mabuchi-motor.co.jp/cgi-b..._ID=rs_755vcwc
the "BaneBots rs775 at 12 volts" does somewhere barely above 200 watts at 14.4 volts. the 18 volt version does somewhere around 70.
I am fairly sure that the numbers on BaneBots website are inccorrect, they do match up with a larger motor from this supplier.

this is the larger motor, but as you can see it is not sold in a 12 volt version, so the 70 watts is close to what this would produce at 12 volts as well, none of the Mabuchi specs come even close to the BaneBots specs.
