A new XS650 coming soon? The Yamaha XS-V1 Sakura prototype.

From motorcyclists-online.com:

"It will be officially presented at the Tokyo motorcycle show (from Oct. 27 to Nov. 11). In the "revival" style, Yamaha shows us a cafe racer pôwered by a good looking V-Twin engine, this is a prototype (not a concept) so it can be released soon...

In the image of Yamaha’s first 4-stroke model, the XS-1 (650cc), released in 1970. Its design is full of XS-1 DNA, in its simplicity and functional beauty and finds new refinement in a retro-modern aesthetic. It is a model that proposes a very Yamaha and very Japanese vision of premium motorcycling life, bringing together the unique characteristics of a 1,000cc air-cooled, V-twin model with its strong pulse feeling and easy-going running performance in a finely crafted body that is lightweight and slim and defined by a low seat height."
