2007 was the last of the RFS (racing four stroke) engines. 08 - 09 have a new engine design that includes separate oil for engine and tranny. RFS engines have a single shared oil.
also the valve arrangement is different. 08-09 use bucket under shim like a drz. i dont know the terminology but the RFS has a screw with locking nut.-so the valve adjustment is different.
many people consider the 07 a highlight year for this bike.
you get most of the bugs worked out like the 05 gear problem ( fix with 06 ) and also first year of factory plated.
not sure about the 08-09 but the RFS 2000-2007 is highly recommended to run an electric fan - oil cooler - and cush drive if plating ( save tranny )
i think most online community would agree and many consider those 3 essential.
ktmtalk.com may help
doesn't mean anything but i would pick the '07
i ride an '04 with a street lighting kit.
best of luck al
