Ishi208 is right, Body Flicker is just swift-movement technique, although it really includes chakra-enhancement. But I understand, why it's considered as a physical characteristic, - actually, very few ninja are able to perform something without chakra enhancements, it's normal in the ninja world. Besides, Naruto's speed is also amplified by chakra (senjutsu, NTCM, SPSM etc), and comparison of Sasuke's sheer physical speed with no chakra with Naruto's requires all the latter's speed enhancements to be put down completely, which means no modes for him at all. (And they are the actual source of his speed.)
