Compare the lock with the retained seat assembly

The seat lock has its own reference pattern and projection note. Check the existing locking arrangement and surrounding fittings before ordering, without assuming that a broad lock description supplies other locking devices or a shared ignition key.

Check projection as well as the reference

The replacement is described as having a locking mechanism that projects slightly farther than the original. Compare the fitted seat, locking bar and nearby frame pieces before ordering. A listed model match should be considered alongside that explicit difference, especially if the seat or surrounding hardware has changed.

Keep keys and nearby hardware questions separate

The product comes with keys, but the description does not state their exact count or a match to the ignition key. It also does not establish a complete package of hinge and locking-bar parts. Confirm any key requirement and assess the retained hardware before choosing the lock.

Common questions

Is this also a helmet or rim lock?

It is described as a replacement seat lock. The listing does not establish helmet-lock or rim-lock functions, so choose it for the identified seat locking arrangement rather than another locking device.

How many keys are included?

The description says the lock comes with keys without stating their exact number. Confirm the supplied quantity if it matters to your order, and do not infer an ignition-key match from the model application.

Does the lock include the complete seat mounting assembly?

A full seat mounting assembly is not identified in the contents. Compare the existing hinge, locking bar and related fittings separately, and confirm any additional components needed alongside the replacement lock before ordering.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
