These guys are on an entirely different level. The engineering and workmanship in both of these projects is astounding.
The first link, called Frankenviffer, is an entirely custom design from the ground up. The V4 engine is the only dominant feature leftover from Honda. The most notable part of this endeavor is what they call the Hossack front end. This design removes any co-mingling reaction from braking and suspension (ie. brake dive).

The Bimota Tesi uses Hub Steering to accomplish the same thing as the Hossack design. Another unique design and worth a look if you haven't seen it:

The end plans for the Frankenviffer (from what I gather) is to supplement the power source with the 'Torocharger'. This is a supercharger adaption for the VFR that yeilds a 50% power increase! It was created by another individual who is also a member of the VFR Discussion board. The supercharger is Rotrex made and uses almost all custom machined parts and fits nicely underneath the stock fairings. The install, from what's posted, sounds elementary and the kit was on a limited production run for around $4k.

I'd love to have a forced induction motorcycle...somewhere just north of 200hp. For sure an experience like no other.
EDIT: (3/26/09) I misread the Frankenviffer forum, as it turns out the Torocharger, or A&A kit, are not the final plans for this project. Although, that's not to say forced induction hasn't been considered by other means....
