yes, some of the stunts are a little outlandish. but if you're really expecting to see perfectly realistic stunts, with no sense of adventure, why not just watch world craziest police chases? it's the outlandishness towards the end that makes this film as class as it is. as for the bike powered by a rolls-royce engine, yes it really is powered by a rolls royce HELICOPTER engine to be precise, and yes it is a real, roadworthy motorcycle, produced by the company MTT, the model is Y2K. so nothing outlandish about how the bike is powered, clearly doghunter1 you have not done much research into this vehicle prior to commenting on its craziness. i felt the storyline behind the film was very good, and the whole atmosphere of it. the bikes really made this film, and there were several hot women also.
