12.5mmx25mm 2 pole rotors are only for stock and super stock.
Modified motors are allowed to be any construction as long as they have 1/8" shaft, and fit in a can 36.00mm x 53.00mm. And for racing, SC trucks are allowed to use ANY Modified motor. Stock motors don't have enough power.
Stock and Super Stock are based on the Novak motor design, which is a 3 slot (salient pole winding) two pole motor design with a 12.5mm rotor. Really a bad design IMHO, because it is very very sensitive to timing. ROAR should have adopted a very low inductance motor (like a two pole slotless) for stock and super stock, because those motors are very insensitive to timing -- makes it harder (if near impossible) to cheat.
