Throttle Lock Cruise Controls from Touratech 

www.touratech-u...
The throttle control from Kaoko replaces the original handlebar end weight on your motorcycle. Sometimes referred to as 'cruise control,' this anti-slip knurled screw secures the accelerator in position. This device significantly reduces strain on the right hand during long journeys.
With infinite friction adjustment, you can fine-tune the function to allow the accelerator to be set to decelerate very gently - leaving you enough time to take your hand off the handlebar for a moment without immediately losing throttle, helping your motorcycle decelerate in a gentle and controlled way.
