Motosacoche Motorcycles

Manufactured in Switzerland 1899-1957

A Brief History of the Marque: Motosacoche

Henri and Armand Dufaux founded Motosacoche in Switzerland in 1899. The Geneva factory began production of machines with small bicycle engines and soon advanced to the production of MAG-engined motorcycles of 250cc to 1000cc. Achieving world records in 1927, and racing success in 1928 with a grand prix machine built by Englishman Dougal Marchal and ridden by fellow countryman Wal Handley, the marque became enormously successful in the interwar period.

World's Records Claimed
PARIS, September 29
Marchand, on a 550 c.c. Motosacoche motor-cycle, claims to have beaten the world's 50-mile and 100-kilometre records at Montlhery, achieving the former distance in 29min. 37.85sec, and the latter in 33min. 26.49sec.

Trove NLA

Motosacoche had factories in Switzerland, France and Italy, and supplied MAG engines to other manufacturers including AJW, Allegro, Brough Superior, Clement... see MAG Engines for a more complete listing.

The French factory was established in the 1920s to overcome the problems with exchange rates, as the Swiss-built machines were becoming too expensive for the French market. The French factory is discussed here: Motosacoche France

Bonjour, je possède une Motosacoche BL 250 de 1928 , moteur MAG importé de suisse et fabriquée à Lyon. Auriez vous des infos sur ce modèle ou documents à me vendre. Je recherche aussi les RAL pour le vert et le violet/ grenat.
Cordialement, Olivier Pachet
Hello, I have a Motosacoche BL 250 from 1928, MAG engine imported from Switzerland and manufactured in Lyon. Do you have information on this model or documents to sell me. I'm also looking for RALs for green and purple / garnet. Sorry, have no further information on the model at present. Do not understand the meaning of "RAL".

Motosacoche Model 2C - VII 4hp 496cc
I wanted to ask you about the reliability of the mag engine for this model, assuming it is set up well
uk That would probably be best answered by a marque specialist. One of the forums listed on the following page may prove helpful: French Resources. (Sorry, no similar Swiss page as yet).

Tenho motor MAG cuja foto com número de construção envio, agradecendo o especial favor de me informarem de que motorização se trata e qual o valor aproximado para eu vender.

Research / information
I have a MAG engine whose photo with a construction number I send, thanking me for the special favor of letting me know what engine it is and what the approximate value for me to sell.

  • No engine number is visible in the photograph. The engine is badly corroded and has parts broken and missing, so the value would be low. Ed.
    A second image was sent, showing the engine number: 2CVII 31425. The following page does not list this number sequence, indicating that it is possibly a competition engine.

Obrigado pela atenção que me dispensou!

Pensei que tinha enviado foto com o número de motor, que é 2 CV II 31425. Vou tentar enviar foto...

Sim, o aspecto do motor não é bom porque esteve abandonado, pelo menos, 50 anos no sótão de minha casa, ali deixado por meu pai que faleceu em 1970.

Na verdade, o que pretendo é saber através do número do motor quantos c.c. tem, e tentar saber qual o valor aproximado para tentar promover a sua venda ou leilão.

Pode ajudar-me, por favor?

Muito obrigado uma vez mais.


José Manuel Henriques

Thank you for your attention!
I thought I had sent a photo with the engine number, which is 2 CV II 31425. I will try to send a photo ...
Yes, the appearance of the engine is not good because it was abandoned, at least, 50 years in the attic of my house, left there by my father who died in 1970.
In fact, what I want to do is to know from the engine number how many d.c. have, and try to know the approximate value to try to promote your sale or auction.
Can you help me, please?
Thank you very much once again.

  • Sorry, cannot give a guide to value. Yesterdays list a 1912 Gladiator with a 2CVII engine of 495cc.

Motosache Mag 1c9 K10
I'm trying to identify the year of production for this engine, any guidance would be appreciated. Serial number is 604217. I have attached a couple of photos.
Darrell Henigman

  • An engine with the prefix 1C9K10 was fitted to a 1929 Model 413 500cc Motosacoche offered by Yesterdays. A post on a Swiss forum reads, "the engine was very probably built in 1930 in a Motosacoche motorcycle type 413th At least I've already seen 8 pieces of such motorcycles that had all your 1C9K10 installed. Also, I have seen 3 pieces of Condor, Type 322 Populaire. They were vintage 1931 and 1932."

Dear Mr. Emu,
my name is Sandra. I just found your website, it is amazing ! I am doing some researches on Motosacoche with the ambition of making a book. I was wondering, if besides you, you could recommend any person with documents or original pictures of Motosacoche. And Even collectors of old Motosacoche. I have met several already in France and Switzerland, but no one in the UK. I thank you in advance for your help.
Best regards.

Removal of entry
Motosacoche R14 1929
Good morning.

You were good enough to place a plea for me ( Jan 25th 2007 - Motosacoche ),

I have now managed to complete most of my research and know what the machine is. I have also managed to get the bike fully registered.

I enclose some photo's that you may wish to use - there are others on Flickr : Motosacoche Staub ( search ).

The bike - I firmly believe - is a 1929 Motosacoche-France Special. Not made for the market but for testing various Bloc-Moteurs prior to decisions being made on a suitable candidate being chosen for a new motorbike. This is during the interim period when New-Map purchased Motosacoche-France.

If you have an interest in expanding your Motosacoche Section then I have an article that only requires finishing and credits added. This gives a suggested history of Motosacoche-France/New-Map around 1929-1930.

Kind regards

Kim Vernon

About the mystery pioneer single monocylinder engine shown on your site, I think it's a Motosacoche 1905 MT which has a atmospheric inlet and mechanical exhaust (225 cubic centimeters). Another version has been built in 1907 but this one is the former one.
All my best

Motosacoche 1910 listed on Ebay UK
Vendor's Description:
This is your chance to purchase and own a veteran motorcycle at an affordable price . This little 4 stroke machine uses a motosacoche unit fitted to little more than a bicycle frame ! So is interesting to ride !!

It has been on the pioneer run and comes with a pioneer certificate that validates this machine as 1910 .

It runs well, has a lighting kit which I have never used and is a good entry for the pioneer run as it is very rare . You see lots of triumphs etc but I am told very few Motosacoche have survived .

If you have a query about Motosacoche motorcycles please contact us
