Hey guys, so my weapon of choice for 2014 is an 05 rmz 450 & since I'm getting pretty serious in motocross I picked up a practice bike (07 rmz 450) any known major diffrences between the two? Here's my bikes. I know the shrouds & rear number plates are different. 05 plastic matches up perfectly. Already have a matching kit for it thanks to my great sponsors (: any info would be appreciated !
