The Italian made Domino twist throttle is high quality with a five wire output and a built in micro switch for added safety. The potentiometer can be configured in a 2 or three wire mode outputting either 0-5K or 5K-0 ohm.
The potentiometer in this model is weather sealed to IP67. Domino offers an identical model that is IP54.
IP67 = Dust proof & water proof to 10 feet under
IP54 = Limited dust protection & water resistant to splashes
Compared to the Magura twist grip which is also 0-5K, the Domino offers higher build quality. The grips are of a softer more comfortable rubber and the throttle motion range is slightly less which is more comfortable on the wrist.
