1971 Honda CB500K · Pistons & rings Buying guide

Choose the package after measuring

The complete kit combines a piston, rings, pin and clips. The ring set supplies rings for one piston, while a genuine Honda pin is listed separately. These choices should follow the condition and size of the existing assembly.

Parts to consider

Standard size describes the offered part

The 56 mm kit is the catalog standard-size choice. That label does not establish what is inside an engine that has already been rebuilt. Ask your engine builder to confirm the measured cylinder and required piston size before deciding how many kits to buy.

Avoid buying the same contents twice

The complete piston kit already lists rings, a pin and a pair of clips. The separate ring set and pin serve different purchasing needs. Build the order cylinder by cylinder, so a parts-only repair does not become an unnecessary stack of overlapping packages.

Questions about pistons & rings

What should I measure before choosing standard pistons or rings?

Confirm the actual bore and piston dimensions, including any earlier machining. The offered piston is standard 56 mm; its model-year application cannot establish that a worn or previously overbored cylinder still needs that size.

Should I order the piston kit or separate ring sets?

The kit supplies one piston, rings, a pin and two clips. The ring-only listing services one existing piston. Four of the chosen one-piston packages are required when replacing those components in all four cylinders.

How do I count pins and clips when buying the parts separately?

The Honda pin is sold individually, and the clip package contains two clips for one piston. Complete four-cylinder replacement needs four pins and four clip packs. A standard piston kit already includes its pin and two clips.
