Welcome to the Forum.



From the photos, these would appear to be Mototrans parts. Mototrans was a Spanish/Catalan company, based near Barcelona which manufactured motorbikes under licence from the main Ducati factory in Bologna, Italy. Mototrans made bikes from 1957 to 1983. Most of their bikes were sold in Spain, with very few coming to Britain. The Mototrans bikes are not exactly the same as Italian made bikes, with many parts not interchangeable.



May I suggest you try to locate in Spain a specialist in Mototrans products who could take a look at the parts you have and advise a course of action?
