ps. the bike belongs to arty goddards wife who worked for many years at goddards in high wycombe a mz and cz dealership any help at all with either prices or avalability would be greatfully appreciated del

Hello

The system of the part numbers is as following:

11-11.111

So if you put a dot instead of "-" you wil not find parts for example on google...

All parts are available.
But I don´t know if you are willing to order from germany.
As I am not so familiar with geography I don´t know where "high wycombe" is located.
As this is an international forum it would help if you say where you are located (country would be sufficient)
