The Jawa Supreme 2 is a top-tank moped based on the Jawa 207 frame and engine. Almost all of the parts are interchangeable with the Jawa 207, with the exception of the tank and seat. Stock 207 cables may also be too long for the Supreme 2.
The cylinder and head are also different from the regular 207 engine found on the step-through bikes, as it doesn't have the decompression lever/system. All other specs are identical to the other Jawa 207 bikes.
