Riding Side Saddle.

Via The kneeslider

"Did women ever really ride motorcycles like this? ased on the 1967 vintage ads shown here but I don’t ever recall seeing women cruising down the street with their significant other, feet swung to one side, resting on the rear peg. At least one company thought they did this often enough to market a footrest specifically designed to keep women’s feet comfortable on a wide platform that could be flipped up out of the way when their man was riding solo."

....Although in Cambodia it's done all the time, fancy footrest or not.
