Yup..you win. All the Pro's here that build them to race and have been building the GY6 50 engine for years..cannot beat that. 7,200 rpm at 50+ mph is good..I can't even come close. But..if your Speedo shows it..it has to be right. Did you get a vid of your Speedo readings on your cell phone cam? We would like to see the results. Way to go and congrats!! If that was only 7,200 then redline at 8,000 should get you close to 55? Or in that ballpark anyway..

what about if i have a bad tire. 8,300 rpm

A bad tire? Not sure what you mean. Like it was flat? Confused.That should not make it go fast. Or are you saying it would take 8,300 rpm if the tire was soft? Sum it up if ya would and tell us what you did to hit 50+ mph with a stock 50cc Scooter. We would like to do that too ya know, so no secrets allowed?
