1974 Honda CL450K6 Signal & Reflector Parts

Signal and reflector repairs on a 1974 Honda CL450K6 need the fitted lamp and mounting arrangement checked together. The available screw-on reflector, rubber base and lamp gasket serve different locations, while the related extended rear stay changes the length that must be accommodated.

1974 Honda CL450K6 · Signal & Reflector Parts Buying guide

Check each lamp and reflector mounting interface

The reflector uses a 6 mm thread and the gasket has named matching lamp components. The linked rear stay is 125 mm long; assess the actual lamp, mounting and clearance rather than assuming a standard length from the model year.

Identify the sealing and mounting parts independently

The lamp gasket is paired in the product details with lens 11-2110 and lamp 11-2122. The reflector and its front rubber base are separate components with their own references. Compare each retained assembly before assuming these products form one combined lamp or reflector replacement package.

Measure the extended stay against the bike

The linked chrome rear stay is 125 mm long and lists a CL450K 1974 application. Check that length against the actual mount, lamp and available space. The description’s comparison with a shorter stay does not independently establish the original stay length for this exact motorcycle or export market.

Buying questions

Can I infer the reflector’s thread pitch from the 6 mm description?

The product specifies a 6 mm thread but does not state pitch. Check the receiving mount and obtain the missing thread detail when needed, rather than assuming diameter alone resolves the fitting.

Does the longer rear stay preserve the original signal position?

Its stated length is 125 mm, so compare the resulting lamp position with the installed arrangement before purchase. The current description does not establish the exact original signal position for every 1974 export configuration.

Will the gasket fit a changed signal lamp of similar shape?

Identify the changed lamp and its lens joint. The gasket’s named matching lens and lamp references do not establish compatibility with every similarly shaped housing; compare the actual sealing interface before choosing it.
