Yeah well, KNIGHT RIDER made it because a 4 wheel crime-buster was always going to win out over a two-wheeled vigilantemobile! Street Hawk's "Harley with attitude" might have had a 200 mph speed capability and a $3 million price tag (bit suss, that one!) but when all was said and done, Rex Smith was no Steve McQueen! More like crime-fighter Disney style.
Best of the offerings, the actual Pilot telemovie entitled STREET HAWK. It ran for 75 minutes and was released in many countries as a one-off video. (I have a copy!) Besides some skimpy background to Street Hawk's existence - The rookie cop, consigned to Public Relations, mega-bike wages war against the local "Mr Big" (Christopher Lloyd in a most un-Disney role). Not only does Jess Mach (Smith) take out Lloyd's cronies, he performs an aerial ballet that sees Lloyd and his 4 Wheel drive nose dive DUEL style off a desert cliff!
Music by Tangerine Dream was certainly a plus, although suspiciously ripped off from the NZ scifi actioner BATTLETRUCK, which coincidentally features a hero riding a superbike!
