About the Honda CM450

Carburetor, engine, brake and fork repair guidance for the CM450, with model and year checks for every linked part.

Honda Motorcycle Logo

The CM450 family brings together the CM450A Hondamatic, CM450C Custom and CM450E. The suffix matters: the A uses a torque-converter transmission, while the C and E use a manual clutch. Use the complete CM450 designation and model year when checking each part.

Shared engine size does not mean shared parts

Some carburetor and rear-brake service items cover all three versions. Fork seals and manual clutch plates have narrower fitments. This family page helps you choose a branch; each model page then groups parts around the repairs relevant to that version.

Prepare for the repairIdentify your CM450 and the fitted part

Check the model code and year

Confirm the complete model code and year from the motorcycle’s identification label or registration. Do not drop the CM450, CM450A, CM450C, CM450E and CM450T suffixes when you check fitment.

Match the part already fitted

Compare the original part with the product photos and specifications. Check markings, dimensions, mounting points, left/right or front/rear position, and the quantity supplied.

Have a part you cannot identify?

Contact PartsNMore with your model, year and clear photos of the part and its markings.

Honda CM450 parts questions

Will the Honda CB450 CM450 Carb Rebuild Kit fit my CM450?
Check the product page for CM450A (1982-83), CM450C (1982) and CM450E (1982-83), then compare the part already fitted. Also confirm carb model, included pieces, jet sizes and year.
Will the same engine part fit every CM450 year?
Not necessarily. The Honda CB450 CM450 Engine Gasket Set fits CM450E (1982-83), CM450C (1982) and CM450A (1982). Check every part separately; one part’s year range does not extend to another part.
How is the Honda CB550 CB450 CB400 CM400 Rear Friction Shoes supplied?
Sold individually. Order the quantity required. The fitment shown is CM450C (1982), CM450E (1982-83) and CM450A (1982-83).
What should I send PartsNMore if I need help choosing a CM450 part?
Send the complete model and year, clear photos of the motorcycle and removed part, any stamped or cast numbers, and useful measurements. Mention replacement engines, forks, brakes or carburetors because those changes can affect fitment.
