The Namura ORNA-RA426539-GS piston rings are specifically designed for the Yamaha YZ 450F motorcycle model, manufactured between the years 2006 to 2009. These piston rings are essential components of the engine that ensure the proper sealing of the piston inside the cylinder during the combustion process.

The rings are made from a high-quality, heat-resistant material that can withstand the extreme temperatures and pressures experienced in a high-performance motorcycle engine. Each ring is meticulously crafted to ensure a precise fit and optimal engine performance.

The set includes a complete set of piston rings, including the compression ring, oil control ring, and skirt rings.

These piston rings have an inner diameter of 94.98mm and are designed to provide excellent sealing and durability, even in high-stress conditions. They are also designed to reduce friction and improve engine efficiency, resulting in improved power and torque output.

The Namura ORNA-RA426539-GS piston rings are easy to install and come with clear installation instructions to ensure a hassle-free experience. They are also made to OEM specifications, ensuring a perfect fit and reliable performance.

In conclusion, the Namura ORNA-RA426539-GS piston rings are an essential upgrade for any Yamaha YZ 450F motorcycle model from 2006 to 2009. They provide excellent sealing, durability, and improved engine performance, making them a must-have for any serious motorcycle enthusiast or racer.
