Honda moped cables have many versions and differences. This is an illustrated spec sheet and price list combined. Showing what all the lengths and specs are allows substitutes to be found or replacements to be made or modified.

1981 Honda NC50 Express
For 1981 the wind-up start was changed to direct kick start, so the rear brake cable no longer had to operate the starter. Also the unregulated oil injection pump became regulated by a split throttle cable.

1978-79 Honda PA50 Hobbit
The PA50 front brake cable angles more upward, like European mopeds, unlike NC50 and Japanese motorcycles. Because of the more direct routing, the cable is shorter.
The benefit of Japanese routing is no interaction with the suspension (going over bumps does not affect the braking), while the benefit of European routing is convenience, because the cable does not hang out and interfere or get damaged.

1980-83 Honda PA50 Hobbit
The ’80-83 PA50 black handlebars are 2.1 inches taller than ’78-79 PA50 chrome handlebars. So all of the cables are 2.1 inches (53 mm) longer. These longer ’80-83 cables fit on a ’78-79 but have to bend forward against the side of the headlight.

NC/NA50 comparison
FRONT BRAKE CABLE – length measurements, calculations and estimations
Treatland conduit length TC is “from top of metal cable end to the edge where the black housing plastic meets the threaded rod adjuster thing”. Myrons conduit length MC is defined by the illustration. So TC = MC – 0.9″
Treatland total length TT and Myrons total length are defined the same. So TT = MT.
Exposed length is calculated. TE = TT – TC and ME = MT – MC. So TE = MT – MC + 0.9 and TE = ME + 0.9″.
TC TT TE upper lower
