This bike is a ball to ride. And why do you need a repair manual? They are put together nice and easy. This is the easiest bike i ever worked on. This bike is designed to use every inch of the tire. It drops nearly like a sports bike, has good get up and go, and even in capable of a wheely now and then (no joke I have done it) although with the slip clutch the conditions have to be just right. Take it from someone who has owned ducattis and Suzuki´s and Hondas this thing is a blast. I don´t know how it compares to other scooters but i never felt the need to find out. it is now my primary bike and 70MPH is no problem. i get spare parts from www.cosmotor.com in PA. Super great guys.
