There are a total of four different engine bearing sets for the Lambretta lui and Junior series. A distinction is made between the models with 4-speed and 3-speed gearboxes. The drive-side bearing differs here:

• 4-speed models (lui 75 and J125 4m) use the 62204 bearing
• All others (lui 50, J50, J100, J125 3m) use the 6303 bearing.

A further distinction is made according to year of manufacture. Up to March 1969, the more complex and more expensive NAO 20-37-16 needle bearing is used, while the 6204 ball bearing is used for models built after this date.

The bearings for the alternator side are not interchangeable and must be used with the corresponding fan wheel housing and crankshaft._{AI-translation}
