1974-78 Honda CB550F / CB550K Standard Size Piston Ring Set ~ Replaces 13011-374-000
Description

Upgrade or rebuild your classic Honda motorcycle engine with this Standard Size Piston Ring Set — designed to replace OEM #13011‑374‑000. This set includes the piston rings needed to rebuild one piston, helping restore proper compression sealing, reduce blow‑by, and improve overall engine performance.

Whether you’re refreshing worn rings or performing a full engine rebuild, these precision rings provide reliable performance and correct fitment for your restoration or maintenance project.

Frequently Asked Questions

How many standard-size piston ring sets are needed for a 1974-1978 Honda CB550F or CB550K engine?

One 58.5 mm ring set replacing Honda 13011-374-000 services one piston. The four-cylinder engine requires four ring sets to replace the rings on all pistons.

Can standard rings be installed without measuring the bore and ring gap?

No. Measure bore wear, taper and out-of-round, then check every ring's end gap in its assigned cylinder. Standard rings cannot correct an oversize or worn-out bore.

What should be checked before reusing the pistons?

Inspect ring grooves and lands, measure groove clearance and confirm the pistons remain within Honda specifications. Install every ring in its marked position and orientation with gaps arranged as the service manual specifies.
