Namura OR-A416649-GS Replacement Piston Rings for 1986-1988 Yamaha BW 80

The Namura OR-A416649-GS piston rings are specifically designed for use in the 1986-1988 Yamaha BW 80 model. These high-quality replacement piston rings ensure a proper seal between the piston and cylinder wall, which is essential for optimal engine performance and fuel efficiency.

These piston rings are made from a durable, heat-resistant material that can withstand the extreme temperatures and pressures inside the engine. The outer compression ring provides a tight seal against the cylinder wall, while the inner oil control ring helps prevent oil from leaking past the piston.

The top ring groove in these piston rings is designed to accommodate the piston pin and piston crown, providing a snug fit that ensures maximum engine power and efficiency. The rings are also precision-machined to ensure a perfect fit and minimize wear and tear on the engine components.

Installation of these piston rings is relatively straightforward, but it is important to follow the manufacturer's instructions carefully to ensure proper installation and avoid any damage to the engine. It is also recommended to use a new piston ring compressor tool to ensure a proper fit and even compression of the rings.

Investing in high-quality replacement piston rings like the Namura OR-A416649-GS is an essential part of maintaining the performance and longevity of your Yamaha BW 80 engine. These rings are designed to provide a long-lasting solution to piston ring wear, helping you get the most out of your bike and enjoy a smooth, reliable riding experience.
