Yamaha YZFR-320cc OEM Piston Rings BR5-E1603-00-00

Description

Yamaha YZFR-320cc OEM Piston Rings  These Piston Rings form the critical seal between the piston and the cylinder wall. A delicate balance exists between proper sealing for maximum power and minimum blow by, and the correct amount of pressure on the cylinder wall to minimize drag which can lead to power loss and excess wear. Additionally the rings help to carry oil up and down the cylinder wall. Fresh rings are a key component when building a high performance engine. We offer a selection of rings for every piston style and diameter. If you are unsure what rings you require for your stock or overbore pistons, please contact us before ordering.

Proper end gaps may need to be set before installation.

FOR USE IN CAST IRON AND NIKISIL CYLINDER BORE
