I'll dig out some details for you, but rest assured there are a fair few differences between a 450 Rally motor and a SX-f motor. I have seen both close-up and personal, including the insides, but even better I know someone that has grafted a 450 Rally motor into an XC-f frame. (Actually it's for sale at the moment and I'll find a link to it for you). There are many considerations that the average punter that doesn't have the "hands on experience" wouldn't even think of.
thanks for the reply. i look forward to your insightful explanation.... wondering what the KTM platform is IF one can't afford the factory 450RR?.....
