Long long ago this lil handy device was "loaned" to me on a ride. My throttle fingers were going to sleep (CTS) and my buddy dug around under his seat and tossed this cruise control device at me. Worked so well I'm still waiting for him to ask for it back and that's been 20 years ago.
It clamps high on the twist grip next to your thumb and fore finger. You just turn the screw until you have just enough pressure to hold the throttle.
When not in use and the throttle off, it's resting just on the brake lever. When you decide you want some cruise control to give your fingers a rest, just take your left hand and tap it down to the brake lever and it will hold the throttle right there.
The good thing about it, when you roll off the throttle the device is no longer in play and you have normal throttle again.
