1981 Honda CB750F · Pistons & Rings Buying guide

Choose piston packages from the measured engine

A complete standard piston kit and a ring-only set solve different buying needs. Standard, first-oversize and second-oversize rings are separate choices, with one-piston quantities stated in the ring listings.

Parts to consider

Standard Size (62mm) Piston Kit (07-0184) Standard 62mm piston kitCurrent product description specifies a 62mm piston with rings, pin and a pair of clips. One kit supplies one piston; four kits supply all four.View part 1979-83 Honda CB750 Piston Ring Set ~ Standard Size Standard piston ring setRing-only set referencing 13011-425-004, supplied for one piston.

Select size before selecting quantity

The standard piston kit is currently described as 62mm, while the ring choices are standard, +0.25mm and +0.50mm. Those are purchasing choices, not instructions to change the cylinder size. Use the measured piston and cylinder condition from your repair assessment before deciding which listing belongs in the order.

Keep complete kits and loose clips distinct

The standard kit includes a piston, rings, pin and two clips for one piston. Separate 15mm pin clips are sold in a pack of two. Check what comes with the chosen piston package before adding loose clips, and keep any ring-only purchase separate from a complete piston replacement.

Common questions

Does one ring set cover the whole engine?

Each of the standard, +0.25mm and +0.50mm listings supplies rings for one piston. Their descriptions specify four sets for all four pistons. Count the pistons being serviced before entering the order quantity.

What comes in the standard piston kit?

The current description lists one standard 62mm piston, its rings, a piston pin and a pair of pin clips. It is a one-piston kit, with four kits specified for replacing all four pistons.

Can oversize rings be chosen to compensate for wear?

Choose the ring size to match the measured piston and the cylinder repair being performed. The two oversize listings are +0.25mm and +0.50mm alternatives; their presence does not establish which size a worn or previously rebuilt engine requires.
