1. Kreidler Models

Kreidler (pronounced kreed-lur) was founded in 1903 as “Kreidlers Metall- und Drahtwerke” (Kreidlers metal and wire factory) by Anton Kreidler. Motorcycle production began in 1951. By 1959, one third of all German motorcycles were manufactured by Kreidler. Visit the Kreidler Museum at

In the 1960’s and 70’s Kreidler became very successful in 50cc motorcycle road racing. With riders Hans-Georg Anscheidt, Jan de Vries, Henk van Kessel, and Eugenio Lazzarini, they were FIM World Champions in 1961, 1971, 1973, 1974, 1975, 1978, 1979, 1980, 1981, and 1982.  Those racing Kreidlers were not mopeds (except the very first one), but they did have the same size pistons: tiny. In 1974 Henk van Kessel did a lap around the Belgian Gran Prix at an average speed of 101.7mph. That is unbelievably fast. Read about 120 mph super-high-rpm 50cc road racers at  Now from one extreme to the other, 120 mph 50cc to 20 mph 50cc:

Mofas and Mopeds In Germany there are two kinds of mopeds:

Mofas are 25 km/h (16 mph), no licence required, minimum age 15, no passengers. German flag“Mofa” is short for motorisertes fahrrad (motorized bicycle).

Mopeds are 40 km/h (25 mph),  drivers license required (any class), minimum age 16. “Moped” is short for motor mit pedale (motor with pedals).

In the 1950’s and 60’s they used the name “Florett” for everything, motorcycles, mopeds, and mofas. From 1969 to 1982, Kreidler mofa models had the prefix MF, while moped models had prefix MP. In the 1970’s the name “Florett” was for top tank motorcycles, mostly 50cc 5-speed. Starting in 1976 the name “Flory” was used for step-thru mopeds and mofas, both automatic 2-speed and manual grip-shift 2-speed types, and “Flott” was for top-tank mopeds.

Kreidler MP 9 Flory moped was the export-to-USA version of a German-model MP 2. Other MP 2 export (non-German) versions worldwide include MP 6, MP 7, and MP 8. Some things are the same. The MP 9 air filter has “MP 8” molded into it. The MP 9 parts price list uses the term “MP 7” for those parts used only on the more restricted MP 9 models. See below “USA Speed Versions”.

Another ZA: The Kreidler two speed automatic (Zwei gäng Automatik) is like a Puch, Garelli or Tomos two speed, with two centrifugal automatic clutches, in a transmission oil bath compartment, one that gets the bike moving forward, and another that lets it shift automatically between first and second (low and high) gear, according to the rear wheel speed. Roughly speaking, below 15mph it’s in first gear and above 15mph it’s in second gear.   

Engine Service: Here is a link to the 1976 engine “Assembly Disassembly Instructions” manual.


This beautiful illustration of an early 1970’s engine is from the 1976 service manual “Assembly Disassembly Instructions”. The front of the engine is facing into the page and to the left. In the views below the front is facing out of the page and to the right. So both the front and the back side of each part are shown, here or there.

3. 1976-81 U.S. Speed Versions

The 1977 MP 9 and MP 19 owners manual says there were four speed versions offered, 17, 20, 25, and 30 mph, for different US states. But none of Myrons Mopeds’s Kreidler brochures or manuals, parts, service or owners, say specifically what parts are on each speed version. The parts catalog is only for 30 mph.

Here is what can be learned from the Kreidler of America, Inc. 1981 Parts Price List and the Kreidler Werke GMBH 1976 Catalog of Spare Parts for MP-9 USAThe carburetor size is always the same 12mm, either early metal-tip-float-needle 1/12/260, or late rubber-tip 1/12/268 which superseded it. There is no other carburetor anywhere in the 1981 USA price list. Other similar Kreidler mopeds and mofas worldwide have 10mm carburetors, such as 1/10/105 or 1/10/126. Besides there being only one carburetor, there is also only one cylinder, one piston, one head, one kind of internal gears, and one intake pipe.

So in the parts price list and catalog, only these four things are different:

Exhaust can be normal 215.23.99 with straight muffler 15.23.74B
Exhaust ca or restricted 215.23.89 with turned-up muffler 15.23.64B
Exhaust    The head pipe, rear cone, and baffle are all the same. 

Intake gasket can be small or big, Ø10 215.03.06 (MP 7) or Ø12 215.03.25 (MP 9) 

Head gasket can be thick or thin, 8.5:1 CR 215.03.30 (MP 7) or 10:1 215.03.44 (MP 9)

Rear sprocket can be big or small, 38T 265.02.12 or 36T 265.02.11 or 36T 265.02.11A

Assuming that the equipment that came on the bikes was in the price list, the speed version differences can be guessed. The guesses are shaded light grey.

30 mph has normal exhaust, big intake gasket, thin head gasket, small rear sprocket

25 mph has restricted exhaust, big intake gasket, thin head gasket, small rear sprocket
25 mphh or normal exhaust, small intake gasket, thick head gasket, small rear sprocket

20 mph has restricted exhaust, small intake gasket, thick head gasket, small rear sprocket

17 mph has restricted exhaust, small intake gasket, thick head gasket, big rear sprocket

All of the other parts on the bike are the same for all speed versions.



4. Frame Parts


The swing arm bushings #2, one on each side, often wear out. The loose swingarm pivot then causes some rear-wheel steering, which makes the bike wobble or weave. There are no replacements available, so far. Here are the dimensions: 14.2mm inner, 17.1mm outer diameter, with a lip 22mm by 2.5mm thick. The swing arm inner space is 81.5mm. The frame outer is 76.0mm.

A tube 14.2 x 17 x 76.5, plus two washers 14.2 x 2.5 would be a simpler, but maybe less precise substitute.
