The custom Lambretta from Supertune was a special dealer custom that was made in the UK in the late-60's. The company Supertune had several versions of their special, and I believe they called this 200cc version the "Rallye." They started with a SX200, and went to town on it. The most obvious alteration was that they lowered the headset down by cutting the fork and the legshield. You can see the difference between the custom and the stock SX200 in the top photo. Then, there is the custom paint, which is quite cool, if you ask me. They also added ball-end levers for safety in competition. On the inside of the scooter, they did some work to the top end. Mainly through porting, and increasing compression by lowering the cylinder head. The idea was that the scooter would still be eligible to compete in scooter racing in the stock engine class. It was a very sweet scooter that commands a tidy sum today, if you can find one of the few that were made.
