Athena 03-07 Kawasaki KX 125 LC 144cc 58mm Replacement Power Exhaust Valve

This Athena exhaust valve kit is what you need to completely rebuild the power exhaust valve on your 2003-2007 Kawasaki KX 125 LC with the 144cc big bore kit. The power valve is crucial for managing your engine's exhaust port timing, which directly affects how your bike makes power across the RPM range. When it's worn out, you can lose performance and responsiveness.

This kit comes with everything Athena recommends for a full overhaul: the main valve itself, the diaphragm that controls its movement, the springs that set its tension, and all the necessary hardware to get it installed. Athena is known for making well-built engine components, and this kit uses the right materials to ensure your power valve operates smoothly and reliably, restoring that crisp throttle response and broad powerband your KX 125 is known for.

Make sure to refer to your Kawasaki service manual for the correct installation procedure and any specific torque values for the hardware included in this kit.
