whats the diff between a aerox and jog motor, i thought that they would take the same rotor kit.pinkymingeo said:Both the .0531 and .0530 are for HMin. The 31 is for Aerox-type, the 30 for Jog-type. Don't be too sure they'll interchange. I got the MVT Aerox-type and it wouldn't run on my Jog-type scooter. The Polini might be different, but it's an expensive gamble.
