1969 Honda CL450K2 Tank Caps & Petcocks

Tank service on a 1969 Honda CL450K2 involves several distinct connections: the cap at the filler neck, the petcock at the outlet and the rubbers supporting the tank. Check the fitted tank before choosing replacement pieces, especially after a tank swap.

1969 Honda CL450K2 · Tank Caps & Petcocks Buying guide

Identify the tank’s fittings before selecting hardware

The chrome cap includes an installed gasket, and the petcock uses an M16 × 1.5 connection. Front and rear tank supports have separate references and should be compared to their own mounting points.

Choose between a complete cap and a seal repair

The chrome cap arrives with its gasket installed; the separate rubber seal is a different purchasing choice. Inspect the existing cap and its seal seat before deciding which repair is appropriate. Do not assume the separately listed seal belongs to every replacement cap.

Account for the tank supports independently

The linked front cushion is sold individually; the listed arrangement uses two. One rear tank-holder rubber is specified per bike. Match front reference 17611-283-010 and rear reference 17613-292-000 to their own mounting positions, especially if the tank or supports have changed.

Ordering questions

Will this tap fit an aftermarket tank outlet?

Only a matching connection establishes the first fitment check. Verify M16 × 1.5 threads, then compare the outlet arrangement and available clearance against the replacement petcock before ordering.

Do I need the separate cap seal with a new chrome cap?

The chrome cap already has its gasket installed. The separate seal is useful only when it matches the cap being serviced; compare the existing cap’s seal seat before selecting it.

Are the front tank rubbers supplied as a pair?

The linked front cushion is sold individually. Two are specified for the listed arrangement, while the rear support uses a different rubber. Count and compare the actual support positions before ordering.
