How to identify your Honda C70

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.
