Easy Rider movie- what are the 2 smaller bikes in the opening scene?

Question

This is the very first scene of the movie, even before the opening credits. I'ts where they score the cocain and hide it in motorcycle batteries. They pull up riding smaller bikes, one sounds like a 2 stroke. This is important to me, please help.
