2 PCS Motorcycle Cruise Control, Stable Carbon Fiber Throttle Mounted Motorcycle Cruise Assist, Handrest Wrist Cruise Assist Grip for Handlebar Relieves Hand Joint Fatigue

I am using these with a escooter than didn't come with thumb controls. I was able to expand the item to fit over the handlebar throttle perfectly and now we have thumb throttle.

Works well all though you need to use a heat gun to form them

the idea is nice, palm of thumb instead of edge of hand but it broke a week later. first time i tried to adjust position, i went to open it up and broke.others had said same but i tried anyways

One was broken at delivery and the other one broke 2nd day on the bike. Would not recommend

I got these as presents for some fellow riders after they saw my throttle assist I use on my Harley. Thes look amazing, but the primarily use the force of them being curled tightly to stay in place when you go to twist your throttle. My more expensive, name brand one has a thick rubber band underneath it that helps it grip to any time of grip you can imagine and is wide enough to fit any type of hand grip. I tried to fit these over my Willie G grips and they would not open enough to get them over the skull. They fit fine on the OEM Harley grips and since those a rubberized they stick well. However, if you have aluminum or really anything NOT rubberized on your grips then I suggest you find some rubber bands to put underneath to keep it from slipping when you want to give your bike a little gas.
