This chart is taken from a list sent to dealers by the factory and lists all modifications to the 650/668 motor and frame, up to frame numer 3032.  I suspect it doesn't cover the very latest bikes, as there have been major changes in the bottom end of the latest 650 motors, to use the 750 cases etc, and these are not listed.  If anyone has access to a later list then I'll gladly include it here.

My suspicion is that this only covers up until some time in 1997, when the Legend and Strike were first introduced.  Also, there is no reference here to the Ghost models.

The references within each description are to the Laverda parts manual and drawings.  Hopefully I will be able to obtain factory permission to reproduce the parts manual pictures on this site at some stage.  Until then, anyone with access to a parts manual will be able to use these references to check against their copies of the manual.  An asterix (*) in the notes indicates that the part number remains unchanged after the substitution.
