The 2013 RM-Z450 received a ton of changes, most of which are unnoticeable while looking at the bike. The bodywork stayed the same but the front number plate is now yellow and the back fender black. This applies to both models making it a bit difficult to tell them apart. The only visual detail that gives these two yellow MXers away is the white side plate handle on the 450 and the black side plate handle on the 250.
