3rd gear gearbox PACEMAKER (Special 150 from 1964) -CASA LAMBRETTA- Lambretta LI, LIS, SX, TV (series 2-3), DL, GP

The more stable 3rd gear for the late PACEMAKER transmission.

From July 1964, the Special 150 was fitted with a reinforced 3rd gear and an adapted auxiliary shaft.

From frame number 94018, the Li 125 Series 3 was also fitted with the more stable Pacemaker gearbox.

The gear also fits as an upgrade for the earlier Pacemaker gearboxes with the corresponding auxiliary shaft. However, it cannot be combined with parts from other Lambretta gearboxes.

However, the close-ratio Pacemaker gearbox itself can be fitted to all engines in the Li family (LI, LIS, SX, TV (Series 2-3), DL, GP).
