( Manufacturer Part Number: 4XV-11631-10-00 ), ( Part Type: Engine Motor Piston )
The Yamaha 4xV-11631-10-00 is a high-performance piston specifically designed for the YZF-R1 motorcycle engine, model years 2002 and 2003. This piston is a crucial component of the engine, responsible for converting the force of the explosion of the fuel-air mixture into mechanical energy.
The piston is made of forged aluminum, a material known for its strength, light weight, and excellent heat conductivity. This material choice allows the piston to withstand the high temperatures and pressures generated within the engine cylinder, while also contributing to overall engine performance and efficiency.
The 4xV-11631-10-00 piston features a compact, flat-top design, which is optimal for high-RPM applications such as those found in racing or high-performance street motorcycles. The piston crown is contoured to ensure proper combustion chamber filling and efficient fuel-air mixture ignition, resulting in optimal power output and throttle response.
The piston also includes a ring pack, which consists of the piston rings. These rings serve to seal the combustion chamber, prevent compression leakage, and control the movement of the piston within the cylinder. The ring pack on the 4xV-11631-10-00 piston is precision-engineered to ensure a tight seal, minimize friction, and maximize engine efficiency.
Furthermore, the piston skirt is designed to minimize piston-to-cylinder wall friction, which helps to reduce engine wear and improve overall engine performance. The skirt is also machined with a precise honing process to ensure a perfect fit with the cylinder bore, ensuring proper sealing and preventing oil leakage.
In conclusion, the Yamaha 4xV-11631-10-00 piston is a high-quality, performance-oriented component for the YZF-R1 engine. Its forged aluminum construction, compact flat-top design, and precision-engineered ring pack make it a reliable and efficient choice for racing or high-performance street applications.
