Another mock-up, but there may be something on the way...
I found out today from a friend in the motorcycle press that Yamaha quietly transferred the production of the XSR700 to the Saint-Quentin factory (where the XT is made) back in October, to be followed by two more models later in 2016.

Read into that what you will? It's most likely that the "two more models" are the MT-07 and the yet to be revealed MT-07 Tracer, but one of them might well turn out to be an XT-07/XT700/XT690...
