Baggy Aluminum Swingarm - Shift lever adjustment

[Randew2U]

Has anyone seen an aluminum swingarm switchout for a Baggy. Talk about weight savings! Ebay is a constant source of aluminum from older bikes being parted out. Wish I knew if MZ morphed the geometry from another production bike.

I dont like the position of the shift lever on my foot and wonder if it is customary to adjust it to fit the rider. I'd like to move it down a bit so that it is easier to get on top of? How about the rear brake lever as well. I wonder if there is an expert bike site that talks more about fitting (adjusting) the bike to the rider? any ideas appreciated.
