1970 Honda CB350K2 · Swingarm Service Parts Buying guide

Distinguish lower shock mounts from the pivot

The 19mm-long bushing serves the lower shock mounting, not the swingarm pivot bearing position. The genuine Honda cap protects the pivot area, while the grease fittings provide a separate service choice.

Order the shock bushings for their actual position

Honda’s K2 parts catalog specifies two 40548-268-000 bushings at the lower shock mounts. The replacement is sold individually, so renewing both requires two. These are not the separate pivot bushes inside the swingarm; identify the source of wear before choosing them.

Keep dust caps and pivot seals distinct

The original K2 swingarm uses two dust caps, with separate rubber seals also shown in the factory catalog. The current genuine Honda cap supersedes the original cap reference. Inspect the existing assembly and do not assume a cap purchase includes every seal or pivot component.

Buying questions

Is the 19 × 22 × 10mm bushing a swingarm pivot bushing?

No. Honda reference 40548-268-000 belongs at the lower shock mounting. The pivot bushes are different components inside the swingarm. Identify where the movement or wear occurs before choosing which bushing needs replacement.

How many lower shock bushings are needed?

The original K2 application uses two lower shock bushings. The replacement product is sold individually, so order two to renew both. If the swingarm or shocks have been changed, compare the existing mounting dimensions before ordering.

Are both pivot dust caps included in one order?

The genuine Honda dust cap is sold individually. The original K2 arrangement uses two caps, so two are needed when replacing both. The factory catalog shows separate rubber seals, which should not be assumed to come with the caps.

Not sure which part you need?
