Anyone, I need a 100cc or 125cc scooter?

I'm quite short, and not very strong, I had a cheap 125 cruiser for my first bike and ended up skidding on some gravel, and injured my knee. I dropped the bike because it's far too heavy for me. Can anybody advise me on an automatic (because of the knee injury) 100cc or 125cc scooters that are light and suitable for someone fairly short. Please help, I really want to enjoy biking again!!!
