Module 3 - Motorcycle Technology Project. Thursdays 7pm til 9pm.
While every effort is made to cover ALL the subjects in the time allowed, this does not always happen. Some areas of each module take longer than others. Suggestions for alternative topics of discussion are welcome.
Members of the class can work on components of their own with prior arrangement.
The workshop must be left tidy each evening in suitable condition for the next class attending.
No formal qualification can be issued by Larkin Community College for any of these modules. However a certificate of completion can be given on request.
