Dogg Thang, it's the Florian Heights track from FUSION, or part of, well that's how it appears to me as it was a unique track in any of the wipeouts and was the only track that had a sections that could be considered "Off Road".

It's the portion of the tracks where the craft are turning right going across a grassy area of park and up a small hill in the VITA version.
In the VITA version it looks like a race playback view, 3rd person, where the Fusion video is in race mode, which is why you might not be seeing the similarities.

That same track in Fusion is bare dirt and a lot of dust is being stirred up by the craft so it's not quite as obvious, but the track takes the same general line and the contours are similar.
