KYB 19-23 Yamaha YZ 65/02-23 Kawasaki KX 85 Piston Ring 36 mm. - 5 Pack

This is a 5-pack of KYB Powersports 36mm piston rings, designed for specific dirt bike engines. These rings are crucial for maintaining proper compression within your engine's cylinders. They seal the gap between the piston and the cylinder wall, preventing combustion gases from escaping and oil from entering the combustion chamber.

When you're rebuilding the top end of your 19-23 Yamaha YZ 65 or 02-23 Kawasaki KX 85, fresh piston rings are a key component. These KYB rings are made to the correct specifications to ensure a good seal, which is essential for engine performance and longevity. Proper sealing means your engine will run more efficiently and produce the power you expect.

Having a 5-pack means you'll have spares on hand if needed, or enough for multiple rebuilds. It's always a good idea to replace piston rings when you're doing other top-end work like replacing the piston or cylinder, as they are a wear item that directly impacts engine health.
