A Brief History of the Marque
Manufactured by the Société Industrielle d’Albert (Somme)
Rochet produced two-speed single cylinder IOE motorcycles from 1902 including an in-line vertical twin and a tri-car. Chain-drive models were introduced as early as 1906, and the unit-construction (bloc-moteur) twin is believed to be the first example of such an engine. These twins were originally of 538cc, inceasing in 1909 to 636cc (6hp).
Three types of machines were made between 1906 and 1910, a 1 ½ HP Legère, a 2 ¾ HP model with water cooling and a 5 ½ HP inline vertical twin. The 1910 catalogue lists Motocyclette Types MG, MI, MH.
The lightweight model weighs about 40 kilograms and has some interesting features, such as sprung front forks and enclosed oil bath rear chain, chain drive being rather uncommon in 1906. The crankcase has a special extension that houses the pedal freewheel. Bore and stroke are 64×68 mm, weight is 40 kilograms and cruising speed is about 40 km/hour. Ignition by Bosch magneto.
The Rochet-Bruneau Type MG had a tandem twin engine rated at 5 1/2hp, a long cylindrical fuel tank mounted between the two upper frame rails, and chain drive.
After WWI the firm was based in Paris and machines were produced until at least 1927.
Rochet engines were supplied to Roland.

Rochet Belt driven
I was recently in the small town of Oatman, Arizona. There is a man that has an original Rochet Belt driven motorcycle on display in their window. They told me it was extremely rare. I could not find any info on this bike.

I have found reference to a Rochet motorcycle being raced in Australia prior to WW1. I am interested in any information on these bikes as I have a Rochet Schneider car. Is there a connection? Is it the same Rochet? Any information appreciated and if you would like details on the article regarding the Rochet motorcycle please let me know.
