I'm looking at buying a 450 XC-f as the basis for a desert race / rally bike. I know the xc-f has the sx-f engine, so my question is how close is this motor to the one being used/tested/raced in the Dakar (and other similarly grueling) race(s).

Thanks in advance for your input.

I take my hat off to you John. By including the bit about "first hand experience" you have cut off 99.5% of the responses you were going get.
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.
Cheers
