It is quite normal in Asia to be more than 2 people on a motorbike (i have often seen up to 5 people!).
This is my friends Pierro with Bun Bun (Chelsea), and Wojtek, riding a Royal Enfield "Bullet" motorbike at the Kumbh Mela 2013 festival, near Allahabad (India).
I ended up using this motorbike for the rest of my trip in India and Nepal.

Kumbh Mela is the largest festival on Earth, taking place once every 12 years, with more than 50 million Hindu pilgrims gathering to pray and bathe in the holy Ganges river.
