1975 Honda CB400F · Piston & Ring Sets Buying guide

Four kits if you are doing every piston

Buy one kit for each piston you are replacing. The product itself says four kits rebuild all pistons in a 4-cylinder engine. It is standard size only.

Parts to consider

Piston Kit with Piston Rings and Pin ~ Standard Size (07-0186) Standard piston, rings, and pinOne piston per kit. Replaces 13101-377-000, rings 13011-377-003, pin 13111-087-000, and clips 94601-13000. The maker says four kits are required for a 4-cylinder rebuild.View part

Do not order one kit for the whole engine

The kit is explicit: it rebuilds one piston, and a 4-cylinder engine needs four kits. Oversizes are not in this product. If you only damaged one piston, one kit matches that job.

Valves are not in the box

Intake and exhaust valves for the 1975-77 CB400F are separate parts, and they do not print a per-bike count. Rings in this kit are the rings for the one piston, not a spare set for the other three.

Piston questions

How many pistons are in the kit?

One, with its rings and pin. The text says four kits are needed to rebuild every piston in a 4-cylinder engine.

What size is it?

Standard. The Honda piston number it replaces is 13101-377-000. Fitment is the 1975-77 CB400F.

Are the clips included?

Yes. Clips 94601-13000 come with the piston, rings, and pin.
