Parts and fitment guide for your 1970 CB100K0

A carburetor service, brake overhaul and oil leak need separate parts lists. For sealing work, compare the four-piece oil-seal kit with the repair before adding individual seals to the same order.

Browse by repair

Selected parts for the 1970 CB100K0

Check the product application, dimensions and pack quantity before ordering.

Identify your 1970 Honda CB100K0

Check the frame identification, engine markings and registration details together. A photograph or paint colour alone cannot establish model year. An engine swap or previous repair can change the parts your bike needs.

Honda CB model guide

Plan the carburetor, brake or sealing repair

The oil-seal kit includes front-sprocket, points-advancer, right-crankcase-cover and gearshift seals. The carburetor kit services one carburetor and lists 1970–72 CB100K. Match the installed carburetor and the location of each seal; a replacement engine needs its own check.

Fitment questions

Does one shoe set cover both wheels? The set contains two shoes and is listed for a front or rear brake. It is one pair, not two pairs; plan the order around the brake assemblies being serviced.

Does an OEM reference mean the part is genuine Honda? Not by itself. Aftermarket parts can quote the Honda number they replace. Look for an explicit genuine Honda description if brand origin matters; “OEM-type” or “replaces OEM” does not identify the manufacturer.
