Honda CB750 - at least the motor is.

I think it is a Honda XL350 from the 1970s modified to bear a passing resemblance to a Harley-Davidson Sportster.

think it must be a Honda XL 500 around 1978-1980

XR500 (longer fork, racing headlight))the twinshocker s model.

1982 Honda CB450T. I own one just like it except that mine was sold new in Canada and has a metric speedo.

Circa 1982 Suzuki GSX450?

Kawasaki A Kawasaki Z1000P police edition motorcycle.

Episode 3.07:

It's a Honda, and the number looks like "185" or something like that.

Honda ATC 185s (its really a 1982)

Ça ressemblerait bien à une Honda XLS 500...

Looks like it with that large (23") front wheel. I owned one of those myself in the '80s.
