Sorry to be a pest, but pictured above are a couple of 750 SS's, customised by Wrenchmonkees and Kiel Kustoms. Their frames look different to the SS frame pictured above. So, were 900SS frames different to 750SS frames? Or did SS frames evolve over the years?
Wrenchmonkees definately modify the frame. the other looks to have been modded too. The carbie SS frames are slightly different to the injected frames but like others have said the ST frames are totally different
