1983 Suzuki CS50 DD Roadie (electric start model)
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.

Sorry, we don’t have any Suzuki CS50 stator plate parts at present.
I don’t know anyone who has one, but I think the Suzuki part number for the part is 32101-02120 (try looking on Google for the part no as it seems to bring up a few people selling it?).
Hello,
I have a 1982 suzuki CS50 without any paperwork. Any chance I can buy paperwork online (or photocopy of it)?

You might want to try asking on a classic bike forum as they usually have members who can help register bikes.
It can be a bit difficult to do by yourself if you don’t know where to get the various certificates or forms needed (can’t really help you any more as it’s been a looonnng time since I registered a vehicle!)……
can I fit a CdI to my Suzuki cs50 roadie delux or is the moped to old
It might be possible, would imagine there’s a fair bit of work and parts involved though…….
