In the States, I believe that there are only two models offered (in terms of the 300)...the "XC" and "XC-W". Both are Cross-country/Offroad/Enduro competition motorcycles. However, it is my understanding that the XC is geared and suspended along the lines of a Motocross/Supercross bike. The XC-W has a wide-ratio transmission, and suspension that is a little more plush (*think desert/Dakar bike).
In the States, the EXC models (450 and 530) are Enduro competition models that also happen to be street-legal. I have been told that their suspension and gearing is more along the lines of the XC-W models. A gentleman below (Wylie) mentioned that they do offer a street-legal version "across the pond". Perhaps that is the 300 EXC. I don't know if they ever offered it in the States (in terms of a street-legal version)...and, if so, what the last year offered was.
I hope this helps...
I dug through www.kbb.com
year by year. It appears there was a 300 EXC model in 2006 that was 2 stroke. 2007 it was called the XC. It will make a big difference to me.
