History of the Marque
Made in France 1917 to 1959 (another source says 1915-1957)
59 rue du Pavillon
MÂCON (Saône-et-Loire).

Well known in sporting circles, the Macon factory - which also produced Koehler Escoffier motorcycles - built numerous Villiers and MAG powered machines up until 1939, and resumed production of smaller motorcycles and scooters after the war, ceasing production in the mid 50s.

Monet Goyon - age verification
Monet Goyon S3G 100
Hi, I tried to register for the forum, but I don't understand the registration comment. I am trying to register this bike in the UK. In order to do so I must have three documents to prove the age of the bike. Ideally to the actual year. Would any of you members have literature they could email me that would do that? Very kind regards

serial number confirmation
Monet & Goyon Three Wheeler
I recently acquired a Monet & Goyon Three wheeled Motorcycle. It was transferred to me under serial number 62623, but I beleive that the first digit is wrong and that it might actually be a "G" or some other digit or letter. Can you verify the typical format for Monet & Goyon serial numbers, and can you identify the year of this motorcycle from this serial number? It was sold to me as a 1921, but it appears to be much earlier, perhaps in the teens, but maybe these bikes were just very primitive designs.

villiers automatic lubrication
Monet & Goyon AS
I have a question about the villiers automatic lubrication system. My engine is a 1929 Villiers MK XA (247 cc). This system includes a vent hole that permits air to pass into the side feed cup from the oil tank. Does somebody know the size of this vent hole ? According to the litterature, "it is very small and should be cleaned with a single strand of Bowden wire", so it could be about 0,5 mm. I have to drill this hole because it is missing in my Motorcycle (Monet & Goyon). Can sombody help ?
Many thanks,

What motorbike is this?
In a shed between Lyons and Grenoble, sits this motorbike. From old insurance papers, we think that it is a Monet Goyon, 4 HP. It was certainly used in 1927 and 1928. Can antone tell us which model it is? What would be the best way of selling it?

The machine pictured has a rear brake, saddle tank, single pushrod tube and what appears to be a speedometer. These would indicate a date closer to the mid-thirties than the mid-twenties, Phil. It certainly appears to be a later model than an HA of 1932.

Can you supply engine and frame numbers, and anything stamped or cast into various components including the crankcase?

The bike is in France and I am in Brighton so getting hold of the numbers will take a while but can be done. There are insurance certificates for my grandfather for 1927 and 1928, one of which describes it as being for a Monet & Goyan bike, 4 HP. We believe that he only owned the one bike but of course, he may have got rid of the Monet & Goyan and bought this one.

Can one use the registration number to track it down?

I am attaching another photo but the first two are better.

Incidentally, there is also a biking cape and soft helmet of the same vintage. The fabric of the cape is a bit stiff but it is basically sound.

Thanks again for your help

Best wishes, Phil Gervat

1949 Monet Goyon
Hi There

I thought you might be interested in this. I bought it in an antiques shop in London today. I haven't collected the bike yet so have yet to scrutinise it more carefull. It is basically pre-unit as it has a 98cc villiers and detached gearbox with hand change. It seems to be very original.

Hi there.
I think I sent you the wrong year for my bike it is actually a 1929 98cc Monet & Goyon not 1949 as stated.

The bike appears to be an S3GD vintage 1949-1954. See Ed.
