1978 Honda CB550K · Rim, Helmet & Seat Locks Buying guide

Compare the replacement lock with the seat already fitted

Projection and reference pattern are more useful buying checks than a general lock label. Assess the seat mechanism, nearby fittings and key requirements without expecting a complete hinge assembly or another type of motorcycle lock.

Parts to consider

Honda CB Seat Lock with Keys ~ Replaces 77230-399-007 Keyed replacement seat lockLock referencing 77230-399-007 and 77230-107-711, with keys. Its mechanism projects farther than the original; exact key quantity and shared ignition-key use are not specified.View part

Include the projection note in the comparison

The replacement mechanism is described as sticking out slightly farther than the original. Compare the old lock and surrounding retained seat fittings, including any previous modifications. That explicit difference belongs in the buying check alongside the model application and listed lock references.

Confirm keys without expecting a whole seat hardware package

Keys accompany the lock, but the description gives no exact count or ignition-key match. The lock also should not be assumed to supply every nearby hinge or locking-bar part. Identify any missing hardware separately and confirm key requirements before choosing the replacement.

Common questions

Is the supplied key matched to the ignition?

The lock description does not establish an ignition-key match. It identifies a lock with keys, so confirm any shared-key requirement before ordering instead of assuming the motorcycle application provides that feature.

Will the lock package include new hinge pins?

Hinge pins are separate seat hardware products and are not identified among the lock contents. Inspect the retained hinge and other mounting pieces independently before treating a keyed lock purchase as a complete seat repair kit.

Can this product serve as a helmet or rim lock?

It is identified as a replacement seat lock. The description does not establish helmet-lock or rim-lock functions, so choose it for the fitted seat mechanism rather than assuming another locking application from the broader category name.
