Honda CB Seat Lock with Keys ~ Replaces 77230-399-007

Honda CB Seat Lock with Keys ~ Replaces 77230-399-007
$28.95 USD
Description

Restore your seat lock with this Seat Lock with Keys, replacing OEM #77230-399-007 / #77230-107-711.

This seat lock works perfectly for the bikes listed; the locking mechanism sticks out a bit farther than the OEM type. If you have lost your old key you have to remove the seat lock bracket and assembly, which can be done with a short 10mm wrench or socket; once that is done the rest is easy.
