I just bought a new vespa LXV 150 (it is a 2009). I was driving it to work for the first time. Going 45 MPH. It is supposed to have a top speed of 59 MPH. My commute is about 5 minutes. But the engine shut off about half way there and I didnĀ“t hit the engine shut off switch. Any ideas why this is happening? Is it over heating? do I need to break it in? Thoughts?
