This movie was the hilariously inept attempt at "good P. R" from the Hells Angels MC, at a time when the club's president was facing a potentially heavy prison sentence, for a yet-to-be-determined laundry-list of criminal charges.
You can see that the director was TRYING to paint a positive (or at least, not TOO negative) picture of HAMC... but the Angels don't make that easy... Generally, they come off as habitually-violent thugs, indignant that they're expected to obey the same laws as the rest of us. Even in this (incompetently) white-washed version of HAMC, we see wife-beating, violence, strong implications of rape, and worse.
That said, although the HAMC are undoubtedly faaaaar from innocent, they also seem to be a magnet for drama- I wouldn't question that, in between the legitimate charges, there very likely HAVE been trumped-up charges levelled against HAMC. And both in the movie, and in real life, I've seen how wannabe tough guys love starting trouble with HA's and other 1%ers (which rarely ends well, for them). Buy hey, play stupid games, win stupid prizes, right? You go around talking about what a super-duper-bad-ass you are, and fly a patch that's basically a neon sign sayng "look at me!!", you can't complain, when you GET the attention you're asking for, can you?
But the timing of this movie was probably fairly good, really- The early 80s was the tail-end of the era when most Angels were still young enough to ride choppers and raise hell- If it was made 15 or 20 years later, you'd have a bunch of retirement-age guys, on stock bikes with big, cushy seats reminiscing about the era from the 60s to early 80s.
