Basic thumb throttle lever/handle
thingiverse
This basic throttle (or other cable activated stuff) lever is meant to be mounted on any handlebars. The main "hole" is 21mm, you can simply upscale the model to fit your handlebar diameter. I personally re-drilled the center hole with my lathe, so beware that a little upscale may be required. I personally don't like the rotating grip kinda throttle levers because you grip on the stuff that controls your speed, during a wheelie or a tight situation, I find it pretty dangerous. This solve the problem to me ! This thing can be improved : some kind of cable adjustment, some kind of stop for the neutral position, a better fixation on the handlebar... Feel free to make a remix ! I provided the solidworks files for easier modifications. Mounted on my mini bike : https://www.youtube.com/watch?v=NRXT-G2S9V4&t=323s
