Assuming Roar rules, a spec motor has specific stator, winding & wire size, and rotor limitations. Modified has a different and far less restrictive rotor limit and not much else beyond the shared can size as far as I am aware.

Page 46 and 47 covers it I think, assuming no missing updates or something else I've overlooked: 2013 ROAR Rule Book
