I've just been to Omega Industries and I've seen what a good place they have for mopeds! Visit http://www.fortunecity.com/skyscraper/binary/1101/motor.htm, there is onfo on all sorts of mopeds and any other bikes in general, but the best thing is you can compare your bike to any other. Besides, there is onfo on how to tune your moped. A must see site!!
