Motorcycle Questions? Ask a Mechanic.
Hi, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.Initially and to my understanding, the Burgman series uses a cable for the seat latch/lock release thus mechanical and not a solenoid hence not electrical so even if the battery is dead, it can be opened.
Proposed preliminary tries (if have not been done):
All others would require access to the cable.
The video HERE would show the cable, linkage and lock.
