I put the KAOKO on my AT (2017) as soon as I bought it.
I use it whenever I have to do more than 30 sec of cruising at the same speed in low traffic. I love this thing because I can fine tune how tight it holds the throttle which I find also helps off road to reduce throttle jerk when riding technical stuff.
I have to say that it was a device that took quite some getting used to.
I developed this action where I slide/drag the outer edge of my right palm over it to lock it. Then when I want to unlock it I grab it with the throttle and decelerate.
The only gripe I would have (if one could call it that) is the fine tuning of the speed to hold the speed limit. Ever so light movements of the throttle change the torque and affect the speed and ever so slight changes in grade of the road do the same.
Definitely not the smoothness of an electronic system, but it has a simple elegance to its function I like. Pretty cheap too.
Why drive when you can ride!
