Yep, Femmoto is for the ladies. Once you are a member you get discounted track days at STT events (guys and girls as participants) and they have the Femmoto Event every year that is a ladies only event.
There is a Femmoto forum I'm on (cycleangels), heard good things about the Las Vegas event. One thing I did hear - there was a couple of members who got their bikes/trailers stolen while there! Now that would suck.
