I have the Kaoko on my V-strom and am still getting used it operating it as I am used to the GoCruise I have on the CB. The Kaoko is definitely a quality piece and I expect I will get used to operating it with my pinky and/or ring finger.
I do echo others in recommending some sort of Palm paddle rest like a Crampbuster. What I don't like about the Crampbuster is how long it is. I have found some alternative products I like better due to a less obtrusive form:
On my CB, I have the Kuryakyn Universal Throttle Boss:
