This article refers to C70 models after 1977 and sold in the UK.
When working on a later model always refer to this article first; where no information is given it can be assumed that the procedure is essentially the same as that described for the earlier models. It is essential to identify exactly the model being worked on; to assist the owner in this, the major identifying points of each are given below with the relevant frame numbers, where available. Where only one frame number is given, this is the number at which that particular model's production run commenced. Note that the frame number is the only accurate means of identifying a particular model. The Z-2 models are largely identical to the original versions, the only significant difference being the fitting of a new type of carburettor with a handlebar-mounted choke operated by cable. The Z-Z models can be identified by the conical-ended silencer. They employed modified components to give a revised gelselection pattern.
The C70-C models are easily distinguished by their two-tone dualseats and restyled headlamp cowling and legshields. They all feature modified air filters, 12 volt electrics and CDI ignition systems. In addition to this, the C90 engine/gearbox unit was completely redesigned and is now exactly the same in layout as that of the C70 model, its new bore and stroke dimensions giving a capacity of 86cc.
The C70-E models, also known as the 'Super Cub' or 'Economy' models, are largely the same as the -C models but feature heavily revised cycle parts with more angular styling and are fitted with larger, rectangular flashing indicator lamps and head lamps; a fuel gauge is fitted and the handlebar controls improved.
|C70Z-2||C70-6115364 to C70-6193904|
|C70-C||C70-8022434 to C70-8039828|

Thank you and stay safe,
Would you be able to send me a picture of that frame number and tell me what's mentioned before said number? You can do that via the contact form.
I have a frame number that only says 2118694.
From what I understood at the shop it doesn't have a CDI system and it has 3 gears.
Should be around 1980.
Thank you for your help
You have a model C70 with the designator C! ;)
Provided that there has not been some engine swap, your frame number is what makes your model.
"The C70-C models are easily distinguished by their two-tone dualseats and restyled headlamp cowling and legshields. They all feature modified air filters, 12 volt electrics and CDI ignition systems."
Now the latter is important in case you wish to order engine parts. Do verify if you indeed have a 12V, CDI system and I'm sure the good people at CMS can help you out then.
Would you be so kind to verify this for me?
