The Ride-by-Wire (RbW) system is an electronic interface between the Monster's twistgrip and engine, which configures an ideal power response depending on the riding mode selected. The twistgrip does not have a throttle cable connected directly to the throttle body butterflies, but instead delivers a signal to a control unit, which in turn operates an electronically controlled butterfly. The RbW system uses three different mappings to regulate power delivery: 145hp with a sports-type delivery 145hp with a progressive delivery suitable for touring 100hp with a progressive delivery for city use
