1979 Honda CB750K · Piston & Ring Sets Buying guide

Decide between a piston package and ring-only service

The standard kit combines several components for one piston. Ring sets are separate size choices, each packaged for one piston. Confirm what the engine needs before selecting a size or multiplying the order.

Parts to consider

Standard Size (62mm) Piston Kit (07-0184) Standard 62 mm piston kitThe current listing includes one piston, rings, a piston pin and a pair of clips. Four kits are specified for all four pistons.View part 1979-83 Honda CB750 Piston Ring Set ~ Standard Size Standard DOHC piston ringsRing set with reference 13011-425-004.

A ring-only order is different from a piston kit

If the work calls for rings without a replacement piston, compare the separate ring listings and their size references. The current standard piston kit already supplies rings, so buying a standard ring set alongside it would duplicate that component unless you have a separate need.

Confirm size before counting packages

The ring listings offer standard, +0.25 mm and +0.50 mm choices; the current active piston kit is described as standard 62 mm. These labels are ordering specifications. Confirm what the measured engine requires, then count packages for the pistons actually being repaired.

Common questions

Does the active standard piston kit include pin clips?

Yes. Its current title and description specify a standard 62 mm piston kit, and the contents list includes rings, a piston pin and a pair of clips. Use that current contents list when deciding whether separate small parts are needed.

How many ring sets cover all four pistons?

The standard and oversize ring listings each state that a set supplies one piston, with four sets needed for all pistons. Choose the size required for each repaired cylinder before setting quantities; the package count does not determine the correct size.

Can I use oversize rings just because the engine is old?

Select the ring size from the actual pistons, cylinders and repair plan. The catalogue provides separate standard, +0.25 mm and +0.50 mm ring options. Motorcycle age alone does not identify which of those listed sizes your engine requires.
