In terms of technical differences and advantages and disadvantages, I am now up to date through my own research. However, I cannot yet tell whether a motorcycle has a carburetor or fuel injection if…

Hello there, I would like to buy a 50cc scooter. I came across the scooter by chance: https://www.hagebau.de/p/gt-union-motorroller-striker-50-ccm-euro-4-schwarz-orange-an671660271/?plaufruf=pl&itemId=B10389405 However, I have a few important questions for you: What is your opinion about the scooter?
