This bike was spotted on the Rocket Garage blog in Italia, who spotted it at one of Europe's bike shows.
Blind-fold any sportbike snob until they sit on this bike. Then, have them ride this thing and I bet their mind would open. I have nothing against the light-weight, high-rev, sport engines.....just highlighting the torque of stroked, air-cooled big twins. When using these lumps, the skilled builder must consider weight in everything. They also have a long drivetrain to contend with (except for Gregg's clever use of the ultra-compact Yamaha engine). The bike below looks like they used a stacked transmission arrangement.
