to be drawn: the frames
look identical (excluding minor bracketry differences) and
their overall dimensions are similar but some of the detail
The 900’s wheelbase is 30mm
longer although the swing arms are the same length, the
extra wheelbase coming from 10mm longer fork length.
swing arm mount is 30mm
higher in the frame in effect lowering the bike.
These combination of changes
were to accommodate the near vertically mounted 900 engine
(the 750’s lent further forward) and improve the bikes
overall comfort and handling.
