It is worth a slightly more detailed explanation than that. We'll use Trinity motors as an example, since they are arguably the most popular Epic-based motors in the US.
When Trinity releases a new motor, the motor is first sold as a regular, packaged version to consumers. In the case of, say, the Revenge of the Monster stock motor, this would be Trinity's part number RC2140.
Then, usually about a month later, Trinity will release a "Pro" version of the motor. These motors have been "tuned" by Trinity's technicians, which means the commutator is freshly trued, the magnets have been re-zapped after coming back from the factory, the brushes are normally a better compound, and the motor has been tested on a dyno, with the results printed on a label and applied to the can. In the case of the Monster motor, this would be Trinity's part number RC2141.
Now, some time after the Pro versions are released, Trinity will release OEM versions of the motors to remanufacturers. These can be purchased (unpackaged) in bulk, at a highly discounted price. Companies such as Axiom will get these by the case, and do their own tuning to them. Unlike Trinity's "Pro" motors, most motor resellers will truly give each one the personal touch: true the commutator, whichever brushes they prefer to use, whichever springs they prefer to use, the armature is "shimmed" (balanced), and then once again the motor is put on a dyno. Adjustments are then made until the motor is as good as it can be.
The difference in price between the regular version and a dyno-tuned version is usually no more than $7-$8, which makes the latter a good buy for racing. For bashing, all you need is the regular version.
Hope that helps out a bit.
