YCC-T (Yamaha Chip Controlled Throttle)

Mechanism characteristics

Yamaha developed the YCC-T system employing the most advanced electronic control technologies. 
Electronic control throttle systems have been used on automobiles, but Yamaha has developed a fast-
er, more compact system specifically for the needs of a sports motorcycle. The Yamaha-developed 
system has a high-speed calculating capacity that produces computations of running conditions every 
1/1000th of a second.
The YCC-T system is designed to respond to the throttle action of the rider by having the ECU instan-
taneously calculate the ideal throttle valve opening and generate signals to operate the motor-driven 
throttle valves and thus actively control the intake air volume.
The ECU contains two CPUs with a capacity about five times that of conventional units, making it pos-
sible for the system to respond extremely quickly to the slightest adjustments made by the rider. In par-
ticular, optimized control of the throttle valve opening provides the optimum volume of intake air for 
easy-to-use torque, even in a high-revving engine.

Aims and advantages of using YCC-T

• Increased engine power

By shortening the air intake path, higher engine speed is possible 

→

 Increased engine power.

• Improved driveability

Air intake volume is controlled according to the operating conditions 

→

 Improved throttle response to 

meet engine requirement.
Driving force is controlled at the optimal level according to the transmission gear position and engine 
speed 

→

 Improved throttle control.

• Engine braking control

Due to the throttle control, optimal engine braking is made possible.

• Simplified idle speed control (ISC) mechanism

The bypass mechanism and ISC actuator are eliminated 

→

 A simple mechanism is used to maintain 

a steady idle speed.

• Reduced weight

Compared to using a sub-throttle mechanism, weight is reduced.
