Would a 80cc 2 stroke be safe to ride on the street and just putting around town? No freeway use of course, and could it cruise at around 45? I am looking for a project and i don't want to put time and money into a bike that I wouldn't be able to ride around town in. Any help would be greatly appreciated. By the way, it is a 1964 yamaha yg1 and looks like a awesome bike .
