Suzuki CS50 Roadie specs…..

The Suzuki CS 50 Roadie was a 49cc, 2 stroke scooter manufactured by Suzuki Motor Corporation and sold in the UK between 1982 and 1988.

The CS50 was marketed as the ‘CS50 Roadie’ in the UK and the ‘CS50 Gemma’ in Asia and was also sold under license as the ‘Puch Lido’ in parts of Europe.
The CS50 was available as a 6 volt scooter with kick start only and a 12 volt scooter with kick and electric start.
Although the CS50 shared many parts with the CS80 (so parts could be interchanged between the 50cc and 80cc models), it was almost completely different to the 125cc model.

    1. You might want to try asking on a classic bike forum as they usually have members who can help register bikes.
