Default any electronic experts out there?

I am trying to install a slightly more powerful motor into the turret rotation unit of my Tammy Pershing.
I found a motor that is the exact same size, and very close amp draw, but with more rpm.

The stock motor is a marbuchi
FF 130SH 14230, 2.5 - 10v, 7400 rpm .050 A
@ max efficiency (6 v nominal) 6060 rpm .23A

The new motor Nichibo
PC-130F - 12240, 3-9 v, 9500 rpm, .10 A
@ max efficiency (6 v nominal) 6800 rpm @ .25 A

The Stock motor has (what I believe is) two resistors.
One from the positive terminal to the negative, then one from the negative to the motor body.
They appear to be the same resistor, with 3 stripes - red, blue, and yellow.

I get that they are probably lowering the power draw from 7.2 to 6 V.
Do I need them?
Do I need different resistors?
I could not even find an image of a 3 stripe resistor.

I am not worried about the motors, as I have 3.
But I do not want to fry my MF or DMD.

Thoughts?
