What does an Ultralumin 7000 aluminum sprocket offer?
The sprocket is machined from Ultralumin 7000 aluminum and anodized. Aluminum weighs less than steel at the same volume, making it an option for riders seeking a lightweight rear sprocket material. Anodizing adds color and helps protect the aluminum surface. The teeth still require the correct chain size and wear inspection during maintenance. The complete sprocket's weight also depends on thickness, tooth count and center cutouts.
Selecting tooth count and chain size
The final drive ratio is calculated by dividing the rear sprocket tooth count by the front sprocket tooth count. Retain the existing rear tooth count when replacing worn parts, or select a different count if you want to change the final drive ratio and have checked the chain length. Available tooth-count options are 45, 46 and 47.
Checking the rear wheel assembly
Provide the wheel part number or a photo of the sprocket mounting points to check this Yamaha version. Compare the mounting-section thickness and back face of the old sprocket. These dimensions affect the tooth position relative to the bike's front sprocket.
