No problem the shafts etc are the same, just check it all fits.
Ther is some difference in ratios, the 750 has different ratios depending on wheather it's a carbed or injected model. Injected model has closer ratios and all but 6th is taller than the carbed model.

The 600 ratios are the same as the 750 carbed model with 2 very important exceptions, 5 & 6th are lower, so if your not interested in top end, and are more interested in the twisties upto 145 >> 150 then its a good swap as you can correct most with gearing. Unless you do a lot at Snetterton, not many tracks call for 150+.

I actually have a 600 tranny in my race bike and I am very happy with how it works it give you a much tighter gear box ratio wise which seems to work out really well with my motor

 

cheers lads.
I have fitted the gearbox and it fits fine. I checked the manual and 5 and 6th are lower which will be excellent as the engine has had some work done and will be used for my Srad streetfighter project.
