YAMAHA : HelmetHangerSet [Q5KYSK056E03]
I was buying a rear bag here and took a look to see what else they offered when I found the Yamaha helmet lock! I received it today and it is the Yamaha part, 4R8-21308-01, which doesn't seem to exist on the Yamaha Parts House site. This part is just the lock and screws however and not the plate. What I received from Webike is the complete set and is already on my FZ1. The helmet lock key is just like my FZ1 key - so when I get my inspection later this month, I'll be asking about getting the helmet lock key keyed to my ignition key.
The replacement bolts for mounting the plate that the lock mounts on are not just longer, they're security bolts - has a raised peg sticking up in the middle of the Torx head so you can't use a normal Torx bit. The one that mounts the lock to the plate is an ordinary Torx since its protected by teh lock itself.
I'd bought a set of security bits some time back to harvest A123 cells from 36v Dewalt power packs to run in my radio controlled stuff, I was pleased that I had what it took. The bit I needed was labeled a T40H. A T30 was needed for the screw mounting the locking piece to the plate. Took all of about 10min.
