I noticed this on one of the first videos too, but I think it was the R25 and the rider was in India riding hard on the track. Anyway, I think it is due to the connector being flimsy and there is nothing to tighten. Just live with it. I had the same thing on my 2012 Triumph Street Triple R. Eventually though, those broke and there was a recall to replace them. These may be fine. If not, it will be a minor and quick fix.
