Vortex rear sprockets are a trusted upgrade for riders looking to replace worn OEM gearing or fine-tune their final drive ratio. A 37-tooth rear sprocket is a popular choice for riders seeking improved top-end performance or a taller overall gear ratio. As with any sprocket replacement, it is recommended to replace the front sprocket and drive chain at the same time for optimal drivetrain performance and longevity.
