Chaise Motorcycles


Made in France
1921-1939

A Brief History of the Marque

Maurice Chaise began his career with Rhone (later Gnome et Rhone) where he worked from 1907 to 1921

One of his engines was a narrow-angle 14° V-four, not dissimilar to the much later Lancia Fulvia. This engine was initially built to power the Majestic, and was eventually produced in capacities varying from 500cc to 750cc. (There is an image in the Majestic gallery of a 1000cc machine but the engine may not be Chaise.  It also powered another of the Delachanal marques, the Dollar.

Chaise engines were used by many motorcycle manufacturers including

    I purchased this motor bicycle. I think it is pre 20's. I got the motor running but it seems to have a fouled plug. Where can I get another of these spark plugs? Any information would be a huge help. Thanks!

      The machine could be one of many brands utilizing the 100cc BMA engine, or it may be a Chaise-built machine. The tank shape should certainly help to identify it - it is quite similar in many respects to the Bretti Bros machine of 1926 in the gallery. Your image of the spark plug is not very clear, but I suspect there will be French and Italian-made replacement plugs available as these engines were built in considerable quantities.

    Chaise K2
    Hi
    I've got an old one cylinder Chaise standing on top of my bookshelter at work. I got it from my father when he passed away many years ago and it has followed me since. Now, could you bring some light into what it is, what it was fitted into etc. I keep it at work because it's technical value, integrated gearbox together with open flywheel a.s.o.
    I would appreciate to hear from you
    regards
    Christer
    P.S.
    The type is "K2", Serie "8" and no "43950"
