CB175K parts by model code
The catalog labels are CB175K3 (1969), K4 (1970), K1 (1971), K6 (1972) and K7 (1973). The 1971 K1 label does not follow the surrounding sequence. Treat it as this store’s label, not as a way to infer the factory designation of an unidentified bike.
1969 CB175K3 · 1970 CB175K4 · 1971 CB175K1 · 1972 CB175K6 · 1973 CB175K7
If your documented 1971 designation differs, send the parts team that designation and the product link before relying on the catalog label. Keep your documented year when checking a listing, even if its K suffix differs from the catalog label.
Use the exact year, not a guessed K suffix
For every year, check the product’s explicit model and year coverage and compare any supplied reference number with your parts information. Keep the original component’s measurements or connection details available if an earlier repair changed what is installed.
