mmmmm, the million dollar question. I have a 2000gsxr750 and have been on the 1000. Now i love the extra torque the extra 250cc gives, but i cant use the stuff ive got with the 750!!!!!!!!!!!! Commuting, the 1000 drinks lots of fuel, the 750 has less kg`s and when ridden properly, will slap the face of any 1000 around hard corners.. Ride both, your choice then,,, in the end it dont matter if you have a little postie bike cause your still on two wheels.
