What's the capacity of a double-decker bus in HK?

Took this picture while I was riding on one of the double-deckers in Shatin, Hong Kong. It belongs to the KMB (Kowloon Motor Bus). Most buses in Hong Kong are long, 3-axle, double-deckers. Many of them are from Germany (Neoplan/MAN, it's supposed to be a famous bus manufacturer), some are from Sweden, and a few older ones from England. If I remember it correctly this picture was taken in a Neoplan/MAN bus. The seats are kinda small compared to those in the United States. Hong Kong people have smaller butts, I guess.
