http://urbanscooters.com/cgi-bin/urbanscooters/SX001.html The Go-Ped Super X-Ped gas scooter is an upgrade of the older X-Ped model. It's packed with all the incredible quality and performance features found on the X-Ped with a few extras. The Go Ped GPL290 Engine features a larger bore and shorter stroke which gives it a much higher RPM, horse power and even ultimate torque at a high RPM. Factory race team grips, double sided fork, and a fatty deck were added to make this scooter the envy of those in the know. The single cylinder, two stroke, air cooled 28.5cc Go-Pedî GPL290 motor puts out 2.5 horse-power and speeds of up to 20mph, but can be tuned and upgraded to reach up to 5 horse-power and 30 mph. This bad boy is for competition use only. The heavy duty aircraft quality steel frame supports up to 400 lbs. The wide, low riding platform gives a smooth and stable ride, and it folds for easy storage and transport. For more information on this scooter, click the link at the top of the description.
