San-Sou-Pap Motorcycles

Manufactured: 1923 to 1936 1

Pantin (to 1930)
114 boulevard de Valmy COLOMBES (Seine) (1930 on)

Under the direction of Henri May, the firm was initially at 212 Boulevard Péire, Paris where they were associated with Motax. They later moved to Pantin.

The first machines were built using DMD twostroke engines, with JAP fourstrokes appearing in 1928.

During the course of production SSP used engines from Train, Stainless, Aubier-Dunne, JAP, Velocette, Triumph (modified), MAG and possibly others.

According to Bonhams:
"...the San-Sou-Pap factory - the distinctive name meaning 'without valves' - was established in 1923, later moving to Pantin where it established a reputation as a good-quality maker of small two-strokes in what was an era of increasing post-war demand for economical transport. Originally using engine units by Ets. Train of Courbevoie, the range expanded with other power-plants, including four-stroke ones, when San-Sou-Pap became part of the Rovin concern based at Colombes. Both San-Sou-Pap and Rovin closed their doors in 1932."

    This machine is a rare example of the SS25A, San-Sou-Pap's last two-stroke model..."

    I would like to find out more information on its pedigree and wether or not it was ever raced.

    I would also like to find out the correct paint scheme for it as the customer may want it restored in the future.San-Sou-Pap-1933-SS25-250cc.

    Hi. I have a wonderfully restored San-Sou-Pap built in 1926. Unfortunately, I have to sell it because I moved to Australia. The bike resides currently in Germany. Can you recommend a forum / classifieds where I could sell it? To my knowledge, there are only two of this bike remaining worldwide... I look forward to your feedback. Kind regards, Robert
