San Sou Pap
114 boulevard de Valmy

Previously at 212 Boulevard Péire, Paris where they were associated with Motax, they moved to Pantin.

Used engines from 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."

    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 1926
    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
