Hello, this is my first post on here, after having searched through this and other, mainly Spanish forums to get some more answers to the many questions I have.
I am from the Netherlands and as you may know, we have a rich moped history overhere. I recently bought a Derbi Coppa Turismo with the intention to get it back on the road after many years of hibernation in a Spanish shed. The bike is 100% original except the Metrakit resonator-muffler with only 4000 miles on the counter but years of abuse and dirt track riding have taken its toll.
The problem is that the era in which the Sport Coppa, Coppa Turismo and Laguna were being built is a bit of a shady period with hardly any documented history. And what you find on the internet is mostly copy paste.
One of the things that is intriguing me is if my chassis number and matching engine number can be linked to a production year. Is there any wisdom available on this site? I have seen a few pictures of chassis and engines matching, mine are funnily enough one off.
I think the Sport Coppa 74 was introduced at the Paris car show in 1980, after which quickly the 49 cc models where introduced including the Laguna and the Laguna TS which were respectively the Sport Coppa and the Coppa Turismo modified with automatic Variant engines to suit the requirements for the US market.
My chassis number is MO34985 as can be seen on attached picture, the engine is MO34984. I have developed a theory that MO stands for Mollet, the village close to Barcelona where the factory was located, 3 being the manufacturing year 1983 and 4985 the production counter. But that again, I entirely made that up.
I will share pictures of the rebuild as is will go along.
