Derbi Laguna, Coppa history

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.

Who cares if the frame/motor are one number off or what exact year it is. Does it affect value, actually its probably much rarer to have one number off than actual matching numbers.

My guess 1984.

I'm getting ready to start my Laguna project, perfect timing. Looking forward to seeing your progress!

Re: Derbi Laguna, Coppa history

The Derbi is due for registration and the Dutch Vehicle Licensing Autorities are keen on this kind of details. If the history is fishy I get no registration and I can't drive it and can't insure it.

Interesting brochures you added to your post! (edited)

Interesting.....

Do you actually need both the engine number and the frame number to match? I would think that only the frame number is important, after all engines are changed all the time, I wouldn't think that would be a problem. (edited)

If you can't drive it and insure it I'm sure someone in the US would pay more than you could sell it for there

Re: Derbi Laguna, Coppa history

You are right, the engine no is not important. It is just that we do a lot with Puch blocks and Puch numbering often reveals interesting details so I was just curious.

Main topic is the history of the Laguna/ Coppa family of mopeds.

Re: Derbi Laguna, Coppa history

That's a really nice Laguna right there! Have fun with the restore!

Re: Derbi Laguna, Coppa history

I don't think "MO" stands for Mollet. Probably something like "motor." I've seen it on other bikes.

A lot of Italian bikes have DGM and OM in their numbers, despite different makers. It's probably just a designation of what type of vehicle it is.

Re: Derbi Laguna, Coppa history

I've been looking over my Laguna's numbers and they seem to match.
