While doing some searching online about converting to a motorbike twist throttle I came across a post where this neat little gadget was mentioned. It doesn't exist yet but man, what a good idea! I really hope it comes out. I've been tinkering with the idea of making something because after a full day of trail riding my thumb feels like its gonna fall off.
