The rotors from the same manufactures stock motors would be the same, it's the stators that are different each time
We'll I would have to disagree with your comment, considering I witnessed firsthand the owner/motor tuner take out my "stock 12.4 mm rotor" and replace it with a 14.0 mm rotor. No changes or modifications were made to the stator, he just switched the rotors and that was it. A few test laps around track to fine tune the gearing and timing and it was running like a top. I never once saw anyone replace their stators, just rotors. Maybe Japanese motors are built differently, I for one don't know what the stator is inside the motor, nor do they state it anywhere on their website or packaging/instructions. Oh well as long a she runs fast
I'll tell you this a 21.5 ROAR "spec" 12.5 mm motor cannot keep up with these Japanese motors unless you replace it with a 13.5 or 14.0 mm rotor.
Even the owner of Xenon mentioned that the D4 with a stock 12.5 mm wouldn't have a chance against the 13.5 /14.0 mm rotors. Thus he will be special ordering a shipment of D4s to japan which will have 13.0 or 13.5 rotors included.
