A Vista Cruise throttle lock is my favorite throttle lock, requiring only a quick flick of the thumb to engage and disengage. The only problem with them is that they are made to be bolted on, and there is seldom really a place to bolt it to. This one was originally on my KLR. I used the glue called Goop which to attach it. It worked great. It may eventually come loose since the glue is adhering to the paint, but it will be easy to re-glue.

I like a LARGE tank bag, if for no other reason than to just have someplace to put water, my gloves or whatever else I might need quick access to. The problem here with most bikes is that when turning the handlebars all the way, the switches contact the bags and the horn will blow, or the starter will spin. These things can really throw you off in a slow tight turn. The best way to fix this is with some sort of guards. There are a few out there that bolt on, but I did not like them. So, Goop came to the rescue again. I cut some aluminum plate and cut holes in it to match protrusions in the switch housing.
