Yamaha Xmax 300 Connecting rod Assy (B74-11650-00)

The Yamaha XMAX 300 Connecting Rod Assembly (B74-11650-00) is a critical internal engine component that links the piston to the crankshaft. As the engine operates, the connecting rod converts the linear motion of the piston into rotational motion at the crankshaft, enabling the engine to deliver power smoothly and efficiently.

This assembly is precisely engineered to Yamaha’s original specifications to ensure correct fit, balance, and durability. It’s manufactured from high-strength material to withstand the repeated stresses of combustion cycles, high RPM loads, and heat inside the engine. Over time and prolonged use, connecting rods can experience wear, fatigue, or distortion — especially if the engine has been subjected to heavy loads, lack of lubrication, or extreme conditions. Replacing a worn, bent, or damaged connecting rod assembly with this genuine-style unit restores proper engine geometry, reduces vibration, and helps maintain optimal performance and longevity.

This part is essential for engine rebuilds or repairs where internal component integrity has been compromised. Using a correctly specified connecting rod assembly is critical for engine balance, smooth operation, and avoidance of catastrophic failure.
