Hello new to the forum and looking some help I have acquired a lovely little 1970's montesa cota been told its a 123 or 172 I have engine number 19MO252 and matches on frame can anyone shed some light on year and model? 

 

Appreciate your help in advance 

It is an early 172 probably 1975 considering the engine number. Others may have more knowledge, but I don't think there is a definitive way to find the year of most Montesa's. They did model runs which may have gone for a couple of years, unlike Japanese bikes. 

Does your bike run?

I rebuilt a 172 recently and they are a great bike to ride. I didn't have any issues finding parts and the piston for these are cheap compared to other Montesa's and Bultaco's.

Add info

Thank you guys appreciate the info can anyone advise parts places in the UK 

I found Inmotion good to deal with. If you need to cast your net a bit wider these guys in Spain are great to deal with. https://www.motosdelabuelo.com/index_en.html . There is an Ebay seller in the USA, Cyclesavant, who is also good to deal with. They bought all of the stock from Rocky Mountain Montesa and Southwest Montesa and have a lot of good used parts as well as NOS. Some of the Ebay sellers want crazy prices for used parts which can be bought new for a fraction of the cost, so it pays to shop around. 

What is the story with the 172 and what do you plan to do with it?

 

If anyone needs a parts list and owners manual for the Cota 172, PM me your e mail address and I can send you one

19M is the model code for the Cota 172. 0252 is the serial number which corresponds to the order the bikes were built in. As mentioned yours would be the 252nd bike built. From what I understand the 172 was released in October 1974 and I don't know how to tell the exact date they were built. Yours is an early one. 

The serial number is important when ordering parts as Montesa updated their bikes from a certain serial number, not by year like most other bikes.

This is a big help COTA172 it will certainly help me with restoration of this one I was also concidering registering it for the road but unsure if this will be a nightmare or not if any help can be given on this.
