i usually always go malossi over polini, but in the variator department, i think polini won out. i have(had) one of each, but never used the polini because i really liked my malossi, and i assumed it was better.
ciaociao tore the malossi one apart after not much riding at all, though.. i was replaceing the broken malossi parts as they broke with parts from the polini, now i'm pretty much rocking the full polini and i like it sooo much better..
