So what does a "Modified" Brushless Motor mean?

An example is Nosram's Pure Evo motor

What makes a brushless motor "modified"? Is it tweaked to provide better performance? Is it better than a non modified brushless motor, by how much?

So if I buy a non-modified motor, can I make it "modified"? How?
Or can I "modify" it? Can someone list in detail what parts of a brushless motor makes it qualify as "modified"?

To my knowledge, the main difference between a stock and a modified motor is the turn value.

Modified motors range from 3T to 10.5T and stock motors are 11T and up.

Look at LRP motors:

In the menu you can see that they differentiate their motors between Stock and Modified and you can see that they are separated by the turn range I mentioned.

You can also see that the stock motors have a different rotor than the modified motors, but seems that is the only difference.

What differences other brands have I don't know.

Hi, thanks for the response.

So 10.5T and lower are considered modified? But how about this YeahRacing 13.5 motor?

and Hobbywing V10 13.5?

Meanwhile in Novak, they have a standard Spec motor and Outlaw (non-roar approved) versions in all popular winds. And they explained the difference of both types in detail. Outlaw versions are more expensive as well.

So are the Outlaws considered as modifieds?

It's just that some rc people brag about their motor being labeled as "modified" and thinks/assumes it's faster.

You can see that YearRacing even call their 21.5T motors modified. Not sure to put too much emphasis on that

Well, in TC a motor 11.5T and higher is stock and 10.5T and lower are modified.

Maybe the stock/superstock/modified term is only a class term (TC, 1/10 buggy etc.) with some requirements on the turn number (21.5T, 17.5T, 13.5T and mod e.g. 4.5T) and some manufactures label their motors stock/modified to identify a relationship to these classes.

Well, if a person brag about a YearRacing 21.5T modified motor, then that bragging will be short lived put against a "true" mod motor (e.g. 4.5T).

I think you are confused because "modified" is the past tense of the verb "to modify". Don't think of them as motors that someone did modifications ("changes") to. They are all manufactured the same way.

You could just as easily call them "Paper" and "Rock" motors. "Paper" are slower and produce less power. "Rock" are faster and produce more power. The words "stock" and "modified" are holdovers from brushed motor days. Even then, the words weren't really applicable because the "modified" motors had no modifications done to them - they were made that way to begin with. It is just a bunch of B.S. naming for people who need simplistic terms.

All this stock and modified stuff comes from the early days of RC. Back then you only really had one motor available, a 27t Mabuchi. So stock was for just that, an unmodified 27t motor. If you pulled the motor apart and rewound the arm with your own wire, that was modified. As things evolved, the two classes became stock for 27 turn, fixed timing, non-rebuildable motors (though rebuildables became a thing later) and mod for any wind and any timing you wanted. This class structure has remained even though the names mean nothing with today's motors.

Better names would be spec for motors that have to comply with ROAR's regulations for "stock" motors and open for open motor rules.

Sounds about right.

Someone I know bought a cheap TRX 10.5 'modified' motor, claims its faster than other 10.5 that's not modified. But my 2 year 10.5 ballistic motor beat it in a dragrace geared the same in a SC truck.

So I think it doesn't matter if its
labeled 'modified' or not.
