Relax, take a deep breath
I noticed this was making the rounds of the Interwebz, so I did some looking around.
Motoblog.it originally published this image of a purported Vespa GTS 400 (That link’s in Italian; the English translation is here). Sorry to disappoint you, folks, but this is a flight of fancy created by someone named Luc; it has no connection to Piaggio or any of its future products.
You probably know the current Vespa GTS/GTV has been around for a while, and that a replacement is due sometime in the near future. All signs point to that replacement sharing the 350 engine with the BV 350, which means that new GTS will get a whole lot bigger because that 350 won’t fit in the current model. Look for 13-inch wheels to maintain the proportions, and most certainly a higher MSRP. It will surely have ABS/ASR, and interface to your smartphone, just like the 2016 GTS and GTV.
Otherwise, nothing to see here, folks. Move along.
