JENAL - Benelli ~ Differences Between Benelli 750 & 900 Sei Frames

750 Sei 900 Sei Rear shock mount centre to swing arm mount centre 334mm 294mm Headstock centre to swing arm mount centre 492mm 462mm Swing arm centre mount to rear end of frame 568mm 568mm Swing arm centre mount to base of frame 159.5mm 139.5mm Headstock depth 160mm 212.5mm Headstock angle 28-30deg 28-30deg Wheelbase 1430mm 1460mm Conclusions to be drawn: the frames look identical (excluding minor bracketry differences) and their overall dimensions are similar but some of the detail is different.  The 900’s wheelbase is 30mm longer although the swing arms are the same length, the extra wheelbase coming from 10mm longer fork length. The 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.
