Fyi - It's a Fantic/Broncco Renegade. They came with 4-stroke 4hp Aspera Engines on them with del'orto carbs. Very nice engines. They also made a very similar version of this bike with a 2 stroke 50cc Minarelli engine, and even a 75cc version (Diablo/Warrior). The 4 stroke Renegade is the harder one to find. I'm in the process of restoring one right now.
