4000 miles on my 2011 Jonway 150cc. Modified slightly. Took off all the pollution control stuff. Alarm and radio are gone, (my choice). Exhaust fell off once. Welded it back together and put it back on. It will reach 55mph, GPS, if I push it. Says 65 on Speedometer. I cruise at 50mph at 7000rpm. Last I checked I was getting 62mpg. Tires still good, but brakes squeak a little. I am real happy with it. I ride it to work and back. Dependable scooter. Only bad thing so far is, I am using duck tape to hold my headlight rim on.
