1970 Honda CB350K2 · Fork Seals & Fittings Buying guide

Check the early fork seal dimensions

Fork seals contain the fork oil, while reflector bases support external lighting hardware. Compare seal dimensions and the reflector mounting independently so a small exterior rubber is not confused with a fork sealing component.

Confirm the forks rather than the frame alone

The seal set is listed for early CB350K forks, including the 1970 application. A later or aftermarket fork assembly can require a different seal. Compare the existing seal dimensions and fork identification before ordering, particularly on motorcycles rebuilt from mixed-year components.

Inspect around the seals while the forks are serviced

Check the relevant sealing surfaces and follow the service manual when replacing seals; a new seal does not correct damaged parts around it. Inspect the external reflector mounting separately, using the rubber base only where its shape matches the installed reflector arrangement.

Buying questions

Does the seal set contain two seals?

The set is presented as a pair, and Honda’s K2 fork application uses two oil seals. Confirm the listed 33 × 44 × 8.9mm replacement specification against the fork assembly currently installed before placing the order.

Will these seals fit forks from a different Honda?

Identify the donor fork assembly and compare its required dimensions first. Being fitted to a CB350K2 frame does not make it an early CB350 fork, and the replacement set should be selected by the actual fork application.

Should I replace only the seals if the forks leak?

Inspect the sealing surfaces and other relevant fork components before ordering. The seal set addresses worn seals, but damaged surrounding components may need separate repair. Use the Honda service manual to plan the inspection and service procedure.
