I have handlebar risers on my ST1300, which put the ignition key down in a well.
On my key ring, as well as the great long Honda key, I have an ID tag (with phone numbers), a top box key and a house key.
Commonly, when trying to turn the engine off, a combination of keys and angles made the task #%^& difficult.
So I cut the red handle off the topbox key and ground it and the house key down to the essentials.
Now they look like this:
No more grief when operating the ignition!
I can use the keyring to help turn the topbox lock if it's a bit stiff.
And a bit less metal in the pocket.
Youse ST1100 guys might lack the security of the HISS system, but your little flat key is a real plus. I used to carry a spare around in my wallet. (another + for you to add in, Streak)
The tumbler ridges on my house key photo were edited to save any enterprising visitor to the site making a copy.
I know, and I'd be less paranoid if everyone stopped following me.
