3. Speed Versions

Sachs 504/1 and 505/1 Speed Version Info, condensed from factory Parts Manuals

Cylinder part numbers and short codes:

0213.146.230 = 0287.137.134 (0287.137.155 black) “D” says “40 km”, square fins, for 504/1C, D, 505/1C, D

0213.146.215 = 0287.137.119 (0287.137.153 black) “A” says “40 km”, angled fins, for 504/1A, ANL, 505/1A, ANL

0213.146.210 = 0287.137.114 (0287.137.151 black) “B” says “25 km”, angled fins, for 504/1B, BS, 505/1B

0213.146.220 = 0000.000.000 (0000.000.000 black) “E” says “25 km”, angled fins, for 504/1A DK

0000.000.000 = 0000.000.000 (0000.000.000 black) “F” says “25 km”, square fins, for 504/1D NL

Case Set part numbers and short codes:

0000.000.000 = 0287.136.402 (0000.000.000 black) “4A” for 504/1A, ANL, C, D

0000.000.000 = 0287.140.203 (0000.000.000 black) “5A” for 505/1A, ANL, C, D

0000.000.000 = 0287.140.215 (0000.000.000 black) “5D” for 505/1D electronic ignition

0000.000.000 = 0287.136.400 (0000.000.000 black) “4B” for 504/1B, BS

0000.000.000 = 0287.140.200 (0000.000.000 black) “5B” for 505/1B

0000.000.000 = 0287.136.408 (0000.000.000 black) “4E” for 504/1A DK

0000.000.000 = 0000.000.000 “(0000.000.000 black) 00” for 504/1D NL

 

The engine cases 4B and 5B are intentionally made different so that the A and D cylinders cannot fit. The cylinder studs are farther inward. That is also why a Sachs cylinder base gasket has slots instead of holes, to fit both types.

To convert a B version (25 km) to an A (40 km) you have to change the engine case set, the cylinder, the intake, the clutch plates, the carburetor, the exhaust, and maybe the sprocket(s). That is too many things to be practical.

Clutch Weight-Spring (ws) part numbers and short codes:

  • weight-spring 0284.015.000 “A” for 504/1A, B, 505/1A, B
  • weight-spring 0284.015.001 “D” for 504/1C, D, 505/1C, D

 

Nationality: The engines are made in Germany, but are sold in different European countries, as well as North and South America and other places. Each country has it’s own laws about how fast and powerful a moped can be. That is why there are so many different speed versions. 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).

This is why Sachs 504 and 505 engine cylinders either say “40km” or “25km”, in the casting.

Where’s the governer? There is not a “governer” yet the speed and power are governed. Several things are intentionally restricted to limit how much air the engine breathes. The cylinder ports open late and close early, the carburetor and intake are small, the exhaust is small. Each thing has about the same influence. Sachs designed it to be tamper-proof, for safety reasons, so unlicensed riders won’t be able to go over 16 mph. No fun intended.

Exhaust header: Different speed versions have different exhaust header pipes. Below the are inner diameters and lengths of the header pipes. The “outer” part of the pipe is the visible part. The “inner” part is hidden inside the tail pipe. Add 2 or 2.5 mm on to the ID to get the OD. So the header that says 26mm is 28 or 28.5 outer diameter.
