In the 1970s, motorcycle racers were no strangers to drugs. But rather than using them - and you can bet a fair few partook - riders, generally privateers, would often find themselves smuggling drugs across continental Europe.

Riders would tour from race track to race track to make a bit of money, largely to keep their (legitimate) speed habit ticking over in the days when race organisers were just as corrupt and steadfastly neglected to cough up any meaningful start money.
