It looks to have 2 CB750's i know one of them is a 77-78 F2 -F3 the other looks to be an 80's model. not sure though

I totally forgot about this video! I agree they are definitely hondas, the comstar front wheels give it away, I am guessing late 70s (78 or 79). I am not sure about the model but could be anything from a 550 four to a cb750 Thats my guess.

Yea. but the other bike is a DOHC. so im thinkin definitely 80's.

I think your right on that one.
