This is Suzuki's ingenious dual-throttle-valve injection system. The primary throttle valve - at the bottom of the photo - was controlled by the rider through the twist grip.
The secondary throttle, above, was moved independently by the engine control unit to help manage intake-air velocity for improved fuel mixing and throttle response.
With this system Suzuki moto produced a fuel-injected bike with the drivability and natural feel that sport riders associated with a welljetted carbureted model.
