I have to agree that it's not real because: 1) it looks too similar to the 660z, 2) the headlights on the official sight are horizontal while the youtube version is vertical, like the 660z, and 3) it wouldn't market for sw-motech's sidecases if it were real.

The second last paragraph is pretty funny, "So as you can see, there’s no need to take the long way round...", a little jab to Ewan and Charlie.
