The Kaoko Throttle Control is a friction device to hold throttle position on a motorcycle.
This can help alleviate cramps and pain on long-distance "superslab" rides.
It replaces the standard handlebar end weight or end cap.
The Kaoko Throttle Control installs easily and the manufacturer has versions for many different motorcycles.
It's more intuitive and easier to use than most of the inexpensive plastic throttle holders we've tried.
Also, the Kaoko device is unobtrusive and made to match the handlebar end weight or end cap for each specific brand and model.
