Motosacoche Motorcycles


Motosacoche was founded in 1899, by Henri and Armand Dufaux, in Geneva, Switzerland.

Motosacoche was once the biggest Swiss motorcycle manufacturer, known also for its MAG (Motosacoche Acacias Geneve) proprietary-engines used by other European motorcycle manufacturers.

From 1900 Motosacoche produced a bicycle auxiliary engine, in a sub-frame that could be installed into a conventional bicycle. This looked like an engine in a bag, hence the Motosacoche name, meaning "engine in a bag".

In 1910, Royal Enfield used Motosacoche 344 cc 2.75 hp engines in a successful V-twin model. They are reputed to have supplied Triumph, Ariel, Matchless and Brough Superior with engines at times too, first through H. and A. Dufaux and then, by 1912, Motosacoche Ltd (GB), with Osborne Louis De Lissa.

Very little alteration has been made in the Motosacoche for next season, for the very simple reason that the machine as a whole has proved so satisfactory and popular that it is difficult to see where improvement is possible. Catering entirely for the believers in handy lightweight motor-bicycles, the "Motosacoche" has come to be regarded as the machine of its class. For 1911 the actual bicycle has been very slightly modified in order to give a better clearance and more perfect alignment for the belt, whilst in addition to this a. belt rim brake. is added. For those who desire a somewhat faster type the company are bringing out a 2.5 H.P. model in which particular attention has been given to the balancing of the engine, with the result that it is, claimed that vibration is completely overcome. This new type is capable of high speeds, and yet, on account of the flexibility of the motor, it will run quite as slowly as the smaller pattern and will start equally easily. Mechanically operated inlet valves are fitted to this type. The ladies "Motosacoche" has been improved, and is designed for moderate speeds, being geared sufficiently low to enable the motor to take the rider up practically any hill on a main road without pedalling. In spite of this there is not the least tendency to overheat.

Motosacoche had factories in Switzerland, France and Italy, and supplied MAG engines to continental manufacturers including Clement, Condor, Imperia, Neander and Monet Goyon.

When the Bol d'Or 24-hour event was first held on the outskirts of Paris in 1922, the winning rider covered more than 750 miles on a 500cc Motosacoche. Sources: Graces Guide
