Motosacoche History

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 racing success in 1928 with a grand prix machine built by Englishman Dougal Marchal and ridden by another Englishman Wal Handley, the marcque became enormously successful in the interwar period.

Motosacoche had factories in Switzerland, France and Italy, and supplied MAG engines to many other manufacturers including AJW, Allegro, Brough Superior, Bayern, Clement, Condor, Dresch, Goricke, Hamlet, Imperia, Lady, Matchless, Monet Goyon, Morgan, Neander, New Hudson, Rex-Acme, Rovin and Royal Enfield. Early Ariel and Triumph models also possibly used these engines.

A 1910 model used the Dufaux engine, according to a post below and Graces Guide.

There is a detailed history of Motosacoche in the UK at the Moped Archive

Further information on a number of models may be found at JLB-Creations

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 .
