Is there anyway I can put an engine from a 2006 CBR 600rr into my 2002 CBR 600F4i?

 

always a way, but is it worth doing? no imo.

 

Search.

And not without serious modification.

 

i really dont think the rr is really better, in terms of speed, it all just depends on which feel you like, but my f4i which is pretty much stock other than a slip on has no trouble keeping up ever
what are the benifits you are looking for by putting in the rr engine? i ask bc a TON of people have been asking that lately, maybe we can direct you to what you are wanting.
