How's this for a crappy title'Chrome and hot leather"
The good guys were army sargents riding dirt bikes.The bad guys including as usual William Smith[who was in heaps of these 3rd rate bike movies] were on assorted chops.
I think they used a lot of chopped Triumphs in the "biker"movies in those days to "fill up" the scenes as they were cheaper than harleys.
Jeez I feel old remembering all this!
