When I was looking for an 1100, my buddy who runs a salvage shop told me this is how he tells the difference.
1100 has dual disk brakes on the front, 650 has a single disk on the front.(some 1100 have been modded to single on the front)
1100 had rear disk brakes and the 650 rear drum brakes.
650 & 1100 are carbed, 950 is fuel injected.
Apparently there is a decal on the left side of the frame with info regarding engine size.
