Aims and advantages of using YCC-I system
• Improved power band.
By using a dual intake funnel system, YCC-I optimizes the effectiveness of the fuel injection system
to deliver an incredibly precise air/fuel mixture to the combustion chamber. This degree of intake vol-
ume control gives both improved low to mid-range power, as well as improved power in the higher
rpm range. In effect, the YCC-I offers higher levels of power across the RPM range.
• Electronically controlled intake length
The YCC-I system consists of four lightweight plastic resin funnels, and each of these is divided into
an upper and lower portion. Depending upon operating conditions, the funnels can be joined to form
a single long funnel, or split to create a short funnel. This change is performed instantaneously by an
electrically controlled servo-motor which handles the function so smoothly that the rider is unaware it
is happening.
