Parts and fitment guide for your 1980 CB650C

This collection brings together listed repair and maintenance parts for the 1980 Honda CB650C Custom. Confirm the exact model and fitted component; a shared CB650 name does not make every Standard, Custom and Nighthawk part interchangeable.

Choose the 1980 Custom carburetor kit

Kit 48-1662 explicitly lists the 1980 CB650C and supplies #90 and #95 main jets, a #59A slide needle, seals and related parts. These numbers describe supplied contents, not a direction to change the jetting. Identify the fitted carburetors and their required specification before choosing which parts to install.

Fitment questions

Can I use the 1981 Custom intake-holder set on a 1980 bike? Holder set 73-0134 lists the 1981 CB650C, but not 1980. Its four holders replace 16211-460-770. Have the 1980 application confirmed against the fitted holders rather than filling the catalog gap with the nearest year.

Which clutch cable listing covers the Custom handlebars? Cable 51-3543 replaces 22870-460-700 and specifically lists the 1980–81 CB650C. Compare end fittings and routing if the bars or controls have changed; its Custom application does not establish the length needed for a modified setup.
