Transmission bearing cross-references

Moto Guzzi Quota 1000 and Quota 1100 ES models

Updated: 

The serial number on my transmission is CM 011978. Both of the double row ball bearings (MG# 92218424) were manufactured with polyamide cages. These are known to fail and can be catastrophic to the transmission and potentially to the rider as well. I replaced both of these bearings with bearings manufactured with steel cages.

All are open (not shielded or sealed).

Note: I have visually verified all of the bearing sizes.
