There is an article on how to make your own cable for the curved tube DelOrto, in the Vintage BMW magazine Classic BMW Motorraeder, March 2021 (Vol 45 No 1). The magazine is available online at

It starts with .048¡± SS stock throttle cable and brass ferrules.

My '75 S has the original curved DelOrto tubes on it. The bike had very low mileage when I got it, and I believe that the throttle cables were original factory.? I noticed that the plastic cable liner was longer by about 1.5" than the outer cable, allowing the liner to line the tube.

I did have a cable break where it curves within the pipe while on a road trip and had to repair it MacGyver style it to get home. I wasn't able to find a BMW replacement cables to replace the broken one, however I had a set of BMW cables modified to match the length of my unbroken cable. Aside from weakening the cable due to the bend, I heard that a problem with the curved tubes is that the cable can cut through it after time. I lube the cable at the tube before rides to protect against it.?

I¡¯ve forgotten the history of curved throttle tubes, but seem to remember they were problematic. Can the learned explain?

Thanks
