Start with your CB100 model designation

This CB100 family covers three model years: 1970, 1971 and 1972. The catalog has both CB100 and CB100K0 labels for 1970, followed by CB100K1 (1971) and CB100K2 (1972). The CB100K range page provides the K-labelled year pages.

CB100K parts, 1970–1972

Check the part, not just the family name

Use the CB100K range to reach the year page for your bike. Keep the full code with the year when checking a listing, particularly for the two 1970 labels. If the product uses a different label from your motorcycle’s identification, ask the parts team to confirm its fitment before ordering.
