what the difference between standard rollers and belt then malossie ones FOR A GILERA 125/172 benifits or loses
ok.. all belts are kevlar. the stock have only one layer tho where as malossi/polini belts are composed of many layers making them longer lasting, less prone to stretching under accel;eration and last longer. the angles on the teeth are a littrle diff too. rollers are better as they are made of harder lighter composits so last longer and dont wear the ramps in the variator as quickly. there also closer tollerance on weight. basicly dont cheap out on belts or rollers. ever
