Can anyone tell me what year motors will fit in my 2004 CRF450R bike. I had engine die and see 2005 and 2008 motors complete and might go that route if they fit. I will rebuild if I have to; however, would rather move to a new year engine.
04-07 motors should fit fine in 08 Honda changed the header pipe so some of the exhaust mounting bracket locations on the frame are slightly different i believe.
just got a message from a guy that said his 05 CRF450R engine will not work in an 04. Not sure if he said that to protect himself because he does not know or what.
