Interesting. The Tesi has fascinated me from the first time I saw one in person, and it's good to see the marque has been pursued and refined.
Also interesting is all of the comments focus pretty much exclusively on crashing! Good grief guys: there is more to be looked at than crash survivability! Take a typical sportbike where a 2 MPH tip over in a parking lot can cost over a thousand dollars to return it to original condition, and it becomes obvious that it doesn't matter how it would fare in a crash, but how it would look like in a garage just waiting to have its owner gear up and go for a good long ride on some twisty roads with a big smile on her / his face.
Obviously not many are going to own one, and that in itself makes it worth doing.
Now if they would put proper bars on it .....
If it has already been done, it is safe to assume it is possible to do it.
On the other hand, if it has not been done never assume it is impossible to do it.

Isn't this how it all starts? They make prototypes, test everything, then someday it becomes mainstream. I guess not all tech makes it's way into mainstream because of costs, but maybe someday this will. Everything was a wild idea at one time.
