1975 Honda CB550K · Engine Buying guide

Planning engine work

List the engine joints you will open before choosing gaskets. Compare the separate overhaul sets, top-end set and shaft seals with the planned work, rather than assuming one kit supplies every sealing part.

Parts to consider

Top end or full overhaul

The Athena top-end set and the two overhaul sets are separate choices. Check the supplied contents against the joints you plan to open; the top-end listing refers to its product photo rather than an itemized contents list. Shaft seals are separately listed.

Choosing piston kits and rings

The piston kit and both ring sets each cover one piston, with four listed for a complete engine. The piston kit already includes its pin and pair of clips. Compare that contents list before adding separately listed pins or clip packs.

Engine FAQs

What bore are the standard pistons?

The standard piston kit is 58.5mm and covers 1974-78 CB550K bikes. It stands in for Honda piston 13101-374-000 and includes rings, a pin and a pair of clips.

Which gasket set suits a 1975 CB550K?

Both overhaul gasket listings name the 1974-78 CB550K. Compare each set's actual contents with your repair plan, including any separately needed shaft seals. The Athena listing identifies its manufacturer; the other set is a separate overhaul option, without an itemized contents comparison.

Does the oil filter come with a washer?

No. The stock-type paper element is sold on its own, and the listing says O-rings, springs and washers are available separately. A five-pack of filter washers is listed for this bike.
