need to know more info of what else you have on your bike. If its all stock and you are just going to add the pulley, either will do. If you plann on adding more parts with time, and want to go all out. I say use the new 9 roller Polini evo pulley. The only thing is with your Jog you are limited on space and if you want to keep the starter motor. If you give more info, we can better answer your question.
