Mars Motorcycles

Address: Sigmundstrasse 40 Nürnberg

The Mars concern was founded in 1873 and built cast-iron stoves, machine tools and bicycles, and built automobiles between 1906 and 1908.

Mars began motorcycle manufacture in 1903 in Nuremberg using Fafnir and Zedel engines. They built the futuristic "White Mars" (Mars die Weisse) in 1921, designed by engineer Claus Franzenburg and fitted with a 986cc ¹ Maybach boxer twin in a box section pressed steel frame. The machine was a true work of art finished to a very high standard and priced accordingly. Production halted in 1924 during the worst of the inflationary period, and resumed in 1926. ²

The brothers Muller resumed production using the MA brand name, and during the 1930s new models appeared with MAG engines and a variety of British powerplants. The company reverted to the Mars brand.

Rudi Albert joined Mars in 1950 and designed the Mars Stella 150 (3) which was deservedly one of the most successful bikes sold in Germany at that time. These were available with Fichtel & Sachs 150 and 250cc engines (and possibly also 175cc.). Mars also employed both JLO and Raleigh engines. The Muller factory production ceased in 1958 and the manufacturing rights were transferred to Gritzner, who continued to produce the marque into the 1970s.

1. Sources vary on the capacity, some giving 956cc, others 986cc.
2. A 1983 Bundespost stamp shows a White Mars with the date 1925.
3. There was a French Stella marque which ceased production in 1953 and is sometimes confused with the Mars Stella. Another Stella brand existed in Italy in the early 1920s.
4. The Aristos used a remarkably similar design, and their frames were possibly supplied by Mars.

Two British made Mars motorcycles are listed:

The Monza Super Sport was introduced by the German motorcycle company MARS in 1957. When MARS closed down in 1958 the production was taken up by Gritzner.
