Sorry this is going to be very vague

in the rely to mid 80’s I saw a film on TV which had a lorry sort of like the universal soldier one but in desert colouring also there was a single motorbike in the film a sort of future looking dirt bike that had discs in the wheels also desert colour I seem to remember the rider had a futuristic helmet  the film was set in the desert I only saw it once as a child but have never forgotten this film probably sent to bed and put the TV on and there it was so never knew what it was called the motor bike did not fly and there was only one kind of knight rider in the desert or something like that
