More photos and start-up video available on request. A known gentleman racer ane custom race bike builder in the Italian "Motor Valley" of Reggio Emilia built it but never finished it completely. I saw it and fell in love with it's build and the idea of having suck a bike to play with.
I had the entire bike gone through, and the electrical system (starting with a new Zeeltronic ECU) was completely redone.
Sadly I'm too tall (I'm 197cm) to properly fit on it, so the reality is that I won't be able to use it although I was hoping to.
As much as I enjoy it as a conversation piece, it deserves to be ridden and cherished as a mad and wonderful toy
