Designed specifically for the R5, R6, and R7 540 sized Team Power Products 2 pole motors.
They have an 1/8" (3.175mm) shaft with engraved part number.
Comes in protected tube with extra shims. If you buy a new R7 motor, and choose the 'Extra Rotor' option, the rotor price is discounted at time of motor purchase!
NOTE: These rotors require experienced motor build skills to install correctly. As with all competition components, there is no warranty!
Consider purchasing a rotor tool HERE. Will make your rotor change process much easier. Have used mine daily for more than six years.

I now have eight sizes of rotors available for the modified winds (12.0mm, 12.3mm, 12.3Stk, 12.5Stk, 12.5Stk2, 12.5mm, 13.0mm, and 13.5mm). Each have a purpose:
Slick Surface Rotor Group
Traction Scale: (compared to TPP55125 Rotor)
High Bite - 0 <=================> 10 - Like Ice
(The BIGGER the number, the less traction available on the surface. Assumes rubber tires on dirt surface.)

- 12.3mm Stock Spec Rotor
-
Alternate rotor for R7 'Stock Spec' motors to exact ROAR rules for use in classes specifying 25.5, 21.5, 17.5, 13.5, & 10.5 'ROAR Stock Spec' motors. Shorter than the rotors TPP57125 or TPP67125 used in Stock Spec classes and has less magnetic field.
-
Alternate Modified rotor on very slippery dirt surface. Will assist motor control when used on slick surfaces. Extremely soft 'feel' when used in R7 modified motor winds; corner exit will have diminished drive out of corners and will need longer run space for offroad jumps.
- Will 'soften up' acceleration in Stock Spec winds.

Stock TRACTION Rate: --
- 12.0mm Modified Rotor
- The smallest option rotor I have for modified motors.
- It has a specific purpose: high speed on large smooth tracks; is its best use on hard tracks.
- Can work with low wind motors on slippery dirt to reduce torque but have higher end.
-
The acceleration out of corners will feel 'very soft'. Requires re-gearing and re-timing to assure motor cooling.
- NOT FOR USE IN STOCK SPEC MOTORS.

12.5mmStock Spec - Standard rotors for R7 'Stock Spec' motors to exact ROAR rules for use in classes specifying 21.5, 17.5, 13.5, & 10.5 'ROAR Stock Spec' motors.
- Shorter than the modified TPP55125 rotor used in modified classes and less magnetic field.

12.3mm - More traditional of the smaller modified option rotors used in modified motors, more torque than the 12.0mm rotor. If you need the high speed of 7.0, 7.5, 6.5, 6.0, and 5.5 motors but need lower torque to keep from blowing tires away during cornering, then this rotor is the ticket.
- Will assist motor control when used on slick surfaces; use TPP57123SP for extreme slick surfaces.
- Top end will be increased and torque will be reduced, compared to a 12.5 rotor. Acceleration, especially low speed corner, will be 'soft'.
- Requires re-gearing and re-timing to assure motor cooling.
- NOT FOR STOCK SPEC MOTORS

-
12.5mm - The most drivable modified rotor with good torque for most tracks and conditions. Very versatile, controllable on slick/medium traction surfaces.
-
This is the rotor you want to use in your modified motors for almost all classes and surfaces. Works best in cars under 65 ounces. Truck based vehicles will also like this rotor in the more aggressive winds like 6.0 and 6.5.
- The 'standard' ROAR rotor diameter.
- NOT FOR STOCK SPEC MOTORS.

- Shorter than the modified TPP55125 rotor above used in modified classes and less magnetic field.
-
Very soft 'feel' when used in R7 modified motor winds; corner exit will have diminished drive out of corners and will need longer run space for offroad jumps.

13.0mm - Option rotor best used for 5.0, 4.5, 4.0, 3.5, and 3.0 drag motors. Have tested them in higher wind modified motors (7.0, 7.5, 6.0, 6.5) on oval tracks with good results; top end will suffer but pulls hard out of corner with an amp draw increase.
- This rotor out torques the 12.5mm rotor by a large margin, will need to use the ESC to add timing as the car speeds up for best results. Careful monitoring of temperature is important. Requires re-gearing and re-timing to assure motor cooling.
- NOT FOR STOCK SPEC MOTORS.

-
13.5mm - Monster torque in option rotors! The airgap is just .5mm (about 0.020"), which really puts the torque to the road!
- Definite loss of top end unless you use the ESC to bring timing in as RPM increases as well as a major leap in amp draw. Drag race specific ESC ot 1/8th scale ESC required.
- Use this rotor for drag racing in 3.5, 3.0 and 2.5t motors. Requires re-gearing and re-timing to assure motor cooling.
- NOT FOR STOCK SPEC MOTORS.
