This article refers to C50 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 C50Z-A model, usually known as the C50L, was fitted with a single seat and carrier, but in all other respects it is the same as the C50Z-Z; to comply with the new legal definition of a moped it had no provision for carrying a pillion passenger. Note: the C50L must not be confused with the later C50LA models which employ a 3-speed fully automatic transmission.

The C50-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.

The C50-E received the same styling alterations and new features described above but was also fitted with a completely redesigned engine/gearbox unit which featured many modifications to improve fuel economy; amongst other new features, a 4-speed transmission is employed.
