Sachs Engine Models

1955 Sachs poster

1. Sachs Engines

Welcome. “Fichtel & Sachs” was founded in 1895 by Ernst Sachs and Karl Fichtel, in Schweinfurt Germany. Ernst Sachs was a racing cyclist and technical wiz, while Karl Fichtel was a business manager. They made hubs and spindles for bicycles and lorries. Ernst Sachs designed and patented a new bicycle hub, the “coaster brake” in 1894, which sold successfully, and also invented the “free-wheel” in 1903. Fichtel died in 1911, and Sachs, in 1932. The first Sachs engine did not come out until 1930.

Sachs introduced their first Saxonette moped in 1937, a 60cc two-stroke 1.2 hp “motor wheel” where the rear wheel and motor were a unit. 320,000 were made in 1937, and 500,000 in 1938. Read more at https://en.wikipedia.org/wiki/Sachs_Motorcycles

Sachs engines have the following numbering scheme:  SSX/YZ(W)

  • SS is the engine size 30, 50, 80, 100, 150, 175 (50 for US models)
  • X is the bottom end designation 1, 2, 3, 4, 5, 6 (4, 5 or 8 for US models).
  • Y is the number of speeds 1, 2, 3, 4, 5, 6 or A ( 1 or A for US models)
  • Z is the cylinder designation, and represents the speed restrictions applied, and may be A, B, C or D
  • W is an additional designation sometimes included on later models and import models to identify other peculiarities. A “K” for example indicates the kickstart version.

Examples:

  • 301/A   is 30 cc size, type “1” bottom end (rear bicycle wheel), “A” automatic transmission
  • 501/4A is 50 cc size, type “1” bottom end (1960’s   kick-start), “4” speed manual trans.
  • 502/2A is 50 cc size, type “2” bottom end (1960’s with pedals) “2” speed manual trans.
  • 504/1A is 50 cc size, type “4” bottom end (1970’s   no pedals), “1” speed, “A” speed version
  • 505/1D is 50 cc size, type “5” bottom end (1970’s with pedals), “1” speed, “D” speed version
  • 508/A   is 50 cc size, type “8” bottom end, (80’s 2sp no pedals) “A” automatic transmission
  • 1005/5A 100 cc size, type “5” bottom end (1980’s   kick-start), “5” speed, “A” speed version
