1157cc is plenty big to get you in all sorts of trouble.
I don't know about getting an '05 KS though. There has been refinements in the later year models that may be worth paying a little more for. Gearbox, final drive, clutch, airbox, etc.
Did you have any issues with your zx-14? If not, be prepared for possible small things (maybe large ones as well) to pop up on the BMW.
'06 K1200R- in pieces
'73 Honda CB500F- slow but fun.
'77 Yamaha XS 750 triple- kinda
