Yamaha Tesseract four-wheeled motorcycle in development?

If you happen to agree with our judgement, we have some good news: recent patent filings indicate that Yamaha may actually intend to build something like this for production.

There are some differences worth noting that separate the machine described in the patent documents from the actual Tesseract concept, notably the use of a parallel twin engine instead of a V-twin and dual shafts driving the rear wheels instead of chains. It's that latter item that makes us think Yamaha might actually be developing this machine, as those conceptual chains would be a nightmare to keep sorted and matched in real life.
