Representing nearly ten percent of all motorcycle owners worldwide, female riders have remained the fastest growing segment in the two-wheeled marketplace for several years in a row. But being a chick on a bike has not always been quite so socially acceptable – especially when you don't like to play by the rules!When Margaret Gast made her first attempt at conquering the Monodrome (a.k.a. 'The Wall of Death') back in the early 1900s, no one would have dreamed of sporting the pink leather chaps or high-healed riding boots found in modern motorbike dealerships . In fact, it would not be until the age of disco when a women named Kerry Kleid fought for her right to race that the AMA gave out its first professional license to a female rider. It probably didn't hurt that she had a reputation of being able to wheelie whatever she was riding...Those pioneering women of motorcycle stunt might just say that girls like Tena "Stunt Blondie" Colbert, JoJo Farmer or Suzanne "Gixxie" Hamilton have it too easy these days. But the truth is, these girls are still raising their front wheels in a largely male dominated sport. And, at least judging by the photos, we don't think they will be taking a back seat anytime soon.

Thanks for the tip Ken!
