No mate its not an emergency brake,This is a fitted piece of kit that immobilises the bike when the key is removed,I think on the european models its called a hiss system,I have a key fob with buttons on but im unsure if this is just to allow for the locking of the trunk etc.If one is fitted it can reduce our insurance in the UK.
Ok I got it now!! No they do not have one installed. It would have to be a self or dealer installed type thing.
Would they accept a simple toggle switch placed inside the trunk area, wired past the main fuse to the starter. Just turn it off, no one would be going anywhere with the bike. Cost would be about five bucks. A switch and some scrap wire, and a couple quick fit crimps.
The Key fob you have is just to lock the trunk and bags. Has no alarm feature.
