Columbia Cables

November 29, 2020

Columbia Commuter mopeds and their alias names had two different frames, stamped sheet metal, or mono-tube, and two different engines, Sachs 505 or Solo 255. All Columbia’s had front and rear hand brakes, with 1970’s Magura controls. 

There are three Columbia cable sets:

a. Columbia sheet-metal frame, Sachs engine, Italian brakes

b. Columbia sheet-metal frame, Sachs engine, American brakes
b. Columbia mono-tube  frame, Sachs engine, American brakes

c. Columbia mono-tube  frame, Solo    engine, American brakes

 


a. Columbia sheet frame with Sachs 505

short throttle cable pipe (most 1976-77)

Italian Grimeca brakes, Italian CEV headlight

 

 

Sachs engine Columbia: On Columbia with Sachs engine, the throttle cable carburetor end passes through a M6-0.75 thread adjuster on the Bing carb elbow, so the adjuster is not trapped on the cable, and is sold separately. The carb elbow, aka curved pipe, can be either short or long. So there are two different throttle cables, short or long. The difference is 1/2 inch of exposed inner wire.
