Power on the Side

At lunch my coworker and I were discussing motorcycles and other two wheeled vehicles. He has a Harley and I will have one when hell and my wife drop below room temperature. The topic of scooters came up and I mentioned this Vespa with 500cc of extra horsepower in the sidecar. It is an odd piece of work since I'm pretty sure you can't fit a grown adult in the sidecar anymore. But hey it should be fun in a straight line at least.
