The Protagonist is a suave, charismatic young man and his girl, ending up being persecuted by a rigid dystopian future state. Some details I remember:
Featuring a possibly sympathetic military officer (who is an old family friend/acquaintance) driving a jaguar.
which gets hijacked on a highway by hooligans. Being military, it's got an emergency button calling in a gurkha special force unit in helicopters. The hooligans are heading straight for organ transplant vats.

on a motorbike, the young man and his girl head out of London north into the countryside, where life is still worth living and people are friendly.
on the way, they have to hide in some cave and sedate themselves to avoid detection by police and their brainwave scanners.
They also do some rite-of-passage by jumping through a ring of fire.
