The grind is different , the X has a mellower profile and is not as aggressive as the R , some people change them for performance gains , it really depends on what usage you want with the bike , if its slow trail or single track riding , the X cam is not as much of a handful of power down low like the R cam is , you may like the R cam profile , I run a HotCams Stage 1 in my 450X and use it for tight single track as well as open desert riding , and i love how the bike responds , though more R cams are best suited for desert type riding when used in a X
Its a matter of , if your happy with the power delivery of the X cam then I would just continue with it , not everyone likes or needs the performance gain you get with a cam swap , not saying the bike will be uncontrollable , it will just have a more abrupt power delivery .... If you can get a R cam cheap , then try it out , if you don't like it , then continue looking for a X cam
