not to shore if this is right section to post but been thinking of swaping rear end e.g subframe for cbr600rr but cant find anything to see if they actually fit so i can fit fairing and seat's straight on so any answers welcome as dont want to waste money on subframe if needs welding here and thair as can do that with original 1 cheers

Anything's possible but the 600rr won't be a straight bolt on. You've probably answered your own question when you say keep the original and butcher that.

cheers m8 i think fount good tut on this site and as you say easier to butcher original so going buy second hand 1 as bike is for everyday use finger's crossed when start
