You've been some good choices guy - - Kymco's & Derdi's are probably at the top of the line in the Moped "speed merchant" catagory. Hopefully in your state they will remain on the approved MOPED List by the State DVM, because they have the last word. But remember just cuz you are on a ped, you are still subject to vehicle speed laws. Cops can nail you deader than 4 o'clock for speeding and reckless driving on a ped. In my area, the Judges are not the least bit lenient to Peds (as in further restricting your ability to obtain a Drivers License).
21 B4 you buy a bike, huh? Okay. Guy, B4 you invest this kind of cash in 1 of these peds you may want to consider, for the same price, a "Classic Muscle Bike" like the mid-80's Honda 250 Rebel (aka a "poorman's Harley"). It'll haul your butt faster and quicker and the resale value is great. Or better still buy an inexpensive used MOPED and save the money for a Hayabusa. Suzuki Hayabusa - - isn't that Japnanese for "Closed Coffin Funeral"? Ok enough joking around. Look, from the voice of experience, going real fast on a MOPED is just plain jackassed dumb. I did it and I am just lucky enought to live to tell it to you. Don't speed on a PED. Been there, and it ain't pretty. Rich
