Here are some pics of my Hybrid I built more than ten years ago.
900SS chassis, modified to use 888 swingarm and rear suspension. Ohlins Corse forks, Ohlins shock, Technomagnesio wheels, carbon fuel tank, titanium everything.
I intended to run it in AMA ProThunder. We built a water cooled 851 2V motor. 900SS cases, 888 crank, ST2 heads and cylinders, custom Carrillo rods. Ported, Hi-comp, etc, etc. But they deemed it wasn't legal, because at the time the rules stated "no water cooled Desmo".
So I shelved that motor and built a super hot 750 motor (as seen in the pics) and raced the bike locally. After the 750 motor ate it's cases, I sold the chassis to Doug Lofgren. He put the 851 2V motor back in, and still uses it as a streetbike today.
