Front half-pulley -MALOSSI Ventilvar Ø 121mm- PIAGGIO Leader, IGET 125-150cc 4T

In contrast to conventional pulleys where plastic fans are screwed onto a steel pulley, here you will find a pulley made from a single casting. The material used is thermally superior aluminum. This results in much better heat dissipation, which leads to fewer slipping V-belts.
