has introduced fly-by-wire technology for the first time ever on
a production motorcycle, the 2006 model YZF-R6.
These CPUs use signals from the
many sensors to regulate throttle valve position for maximum
response and performance in all speed and rpm ranges.
But for a model
with the short manifold necessary for a super high revving
engine such as the 2006 R6 there is not enough room for these
devices. Plus in a high revving engine, smooth torque
characteristics in the low to mid speed range are normally
difficult to achieve.
The YCC-T system
is designed to respond to the throttle action of the rider by
having the ECU unit instantaneously calculate the ideal throttle
valve opening and generate signals to operate the motor-driven
throttle valve and thus actively control the intake air volume.
