Why are the exhaust valves closed at low rpm?
The exhaust valves are partially closed at idle and low rpm to reduce noise, and closed again at the upper RPMs to meet peak noise and emissions regulations. The proof of this has been shown on the dyno where removing the valves and retuning the engine creates a flatter better torque curve.
What does an exhaust servo motor do on a motorcycle?
What does an exhaust servo motor do? An exhaust servo motor is one component of the exhaust valve system (sometimes called the ex-up or power valve system) found on almost every modern sportbike including all Honda, Kawasaki, Yamaha, Suzuki, BMW, Ducati, Triumph and a few others.
Is there a way to bypass the exhaust valve?
Removing or bypassing the valve is quite easy. It can be accomplished as easily as removing the cables that connect the valve to the motor. The valve typically is spring loaded so if disconnected it will hold the valve in the full open position. Additionally, the purchase of a full or slip on exhaust system often eliminates the exhaust valve.
Can a servo Buddy replace an exhaust valve?
The Servo Buddy®, is a small electronic device that replaces the servo motor. By interfacing directly with the engine control unit the Servo Buddy® can emulate a fully functional, stock, exhaust valve and motor system.
What kind of engine does the Honda CBR600RR have?

What’s the difference between CBR1000RR and CBR250RR?
The CBR1000RR & CBR250RR were the models that went under the knife this year with loads of changes last year which led some of us to hoping that 2018 might be “the” year for the CBR600RR and a major overhaul with loads of new changes and technology thrown at it but the CBR600RR returns for 2018 with no mechanical changes or upgrades.
