I ran across this 1977 factory design sketch of Bultaco’s proposed 250cc version Streaker in Francisco Herreros’s history of Bultaco, A Passion For The Sport.
I had seen this before, and even though I was not consciously aware of it, I think it definitely influenced the end goal I had in my head when I started this project. Compare it to this, and there are some vague similarities, especially in the tail.
