Friend on mine has been looking for a WR450 for a while and has only came across thrashed out late model bikes. So he has found a one owner 03 model with genuine 1000km on it. Its super clean and great price. Now is there a hell of alot of difference with the later models? The bike is stock and my mate has been of bikes for several years but can ride good. Or should he just wait for a 05/06 bike?
