Anyway, if you can pull it off (or not) and you would like to save some gas, here is an example of what you can expect. Is it worth it? I would say absolutely, but that really depends on your outlook. Are you interested in the dollar savings only, or are you also interested in how you are helping the environment with your cleaner emissions? Remember, modern Vespa's are squeaky clean and meet all the current emissions requirements with their modern Piaggio designed four-stroke engines. And, if you ask me, riding on two wheels is totally cooler than driving on four!
