is anything as mad as attempting the Paris-Dakar Rally on a quartet of Vespas? (thank you Rich!) The 1980 Paris Dakar rally, had 4!

After spending 23 days in the saddle, two of the Vespas, ridden by M. Simonot and B. Tcherniawsky, made it Dakar and crossed the finish line! Standard Vespa PX200s, seven countries and 10,000km of the most unforgiving terrain imaginable.
