For the original and version II, only Yokomo spurs fit. Smaller sizes used to be available in white color and were intended for the D-Max drift cars. The octagon is the same as AE, the center hole is larger, of course.
SG-4872S e.g. is the 72 tooth version, and there used to be others. Not sure if the B-Max 4 III used the same spur gears, though.

Thank you. I had read somewhere about the D-Max spurs fitting this car, but I have not been able to find any details on it.
