Note: The Jet 200 is basically an SX200 with some small changes. Early models had SX panels, floor runners and typical Italian style air boxes. Later models had different side panels similar to GP type bikes, floor mats instead of runners and a different air filter arrangement visible by intake fins on the toolbox door as shown below. Only very early models were made with an internal disk brake like the Italian SX200s. Bikes after 1982 had 3 lights added to the headset; a green for neutral, orange for low beam, and red for high beam.

Frame and engine numbers start with the SX200 prefix and were usually the same number on the frame and engine.
