In order to lower pollution, Yamaha has developed a new generation of Fi fuel injected engines with the best control strategy. The inlet sensor used by this advanced Fi system can detect the inlet condition change of the engine from the riding environment. The built-in ECU microcomputer can timely and accurately control the fuel injection volume and air-fuel mixture when responding to the external changes to allow the engine to run at its optimal combustion condition no matter where it is.

Low fuel consumption, reduced pollution, and minimal noise are Yamaha's pledge in maintaining the beauty of our environment..
