Gearbox Cover POLINI Evolution
for MINARELLI horizontal
Something new from the POLINI Evolution Series: a reinforced transmission cover. All three gear shafts are guided through ball and needle bearing. This reduces friction and has a positive effect on performance. POLINI has a new ending to the old story of oil smeared dirty gaskets with the use of an oil ring. Simply place in the milled nut to enable quick cover removal. Available for horizontal MINARELLI and PIAGGIO Hyper2 motors (outer mounted primary shaft). Depending on type of transmission for PIAGGIO motor, there a version for 16 mm and 12 mm trans.
