Owner and Service Manual Review

The following service manual applies for Yamaha YZFR1W|WC motorcycle series. In this manual you will find detail information about features, specification, periodic checks and maintenance schedule, chassis assembly/disassembly and repair procedures, detail engine components, diagrams, and service instruction, cooling system, fuel system, electrical system and troubleshooting. The YZFR1W|WC applies YCC-T system.

The YCC-T system is designed to respond to the throttle action of the rider by having the ECU instantaneously 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 three CPUs with a capacity about five times that of conventional units, making it possible for the system to respond extremely quickly to the slightest adjustments made by the rider. In particular, 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. The YCC-I system calculates the value from the engine revolution number and throttle opening rate, activates the intake air funnel with the electronic control motor drive to control the intake pipe length in order to gain the high power output in all revolution ranges from low speeds to high speeds.
