I just got a 2009 WR450. I currently have a 2006 WR450. My question is are the parts different between the bikes? I have a factory connection suspension setup on my 06 and want to put it on my 09. I know the part numbers don't match but are different by 1 number. I know the exhaust won't work but I don't want to lose my custom suspension and rekluse core exp clutch. Any answers?
