The Girl on a Motorcycle (French: La Motocyclette) is a 1968 erotic romantic drama film directed by Jack Cardiff, starring Alain Delon and Marianne Faithfull.

[5] The Girl on a Motorcycle redefined the leather jacket for motorcyclists into a catsuit, created by John Sutcliffe,[6] that Faithfull wore in the film.

During her ride to visit Daniel, her lover in Heidelberg, she indulges in psychedelic and erotic reveries as she relives her changing relationship with the two men.

Cardiff received extensive cooperation from the police in blocking the roads, so many scenes show only the lone motorcycle and no other vehicular traffic.

Faithfull's riding double in medium to distant shots was Bill Ivy, British Grand Prix motorcycle champion.

[9] The Monthly Film Bulletin wrote: "What with Alain Delon morosely pawing the zip on Marianne Faithfull's leather suit and muttering 'Your body is like a violin in a velvet case' while she squeaks 'Skin me!'

with ecstatic urgency, Girl on a Motorcycle will probably thrill countless maidenly devotees of women's magazine pornography.

All the imagery is there, from the darkly passionate stranger (zoom in to hypnotic eyes now and again) to the sadistic ringmaster of fantasy who strips the clothes off his beloved with a cracking whip; and Jack Cardiff pulls out all the lush stops with endless shots of mistily-filtered landscapes, tricksy colour fantasies, and nudging shots of the heroine's bust and buttocks (clad or unclad).

She is required to do little more than sneer, pout and wrap her leather-encased limbs around said bike, but this image alone reduced a generation of males to pop-eyed slavering wrecks.
