How it works. In the most basic sense, RBW inserts a computer between your right wrist and the throttle plates. As you twist the throttle—perhaps we should start calling this something else, like a Thrust Request Device—the ECU takes into account engine speed, vehicle speed, gear selection, and other factors. It then decides how much to open the throttle plates based on a few assumptions of how much power you want. This is no longer a one-to-one relationship between your right hand and the throttle plates; the computer knows better and acts to keep power flowing smoothly. Also, for many years, bike manufacturers have used different fuel and ignition maps for each gear in an effort to tailor, usually by trimming back, power in the lower gears. No longer needed: RBW does this automatically, preventing, in essence, full power from ever reaching the rear wheel in the lower gears. What are the other benefits?
