Confirm the exact model year, output-shaft spline, sprocket offset and chain alignment before ordering. Other special editions require fitment confirmation. Use a matching 520 chain and rear sprocket. Converting from the original chain pitch requires the corresponding drivetrain components.
The image illustrates a solid 17-tooth 525-pitch Y001 sprocket from the same series. Supplied chain width, tooth count, lightening-hole design and appearance may differ according to the selected exact SKU. One front sprocket is supplied; other drivetrain components are separate.
