Vortex sprockets are a trusted choice among street riders, track day enthusiasts, and racers alike. The 840ZRV4-47 rear sprocket is an ideal upgrade for riders looking to improve low-end pull and mid-range grunt without sacrificing durability. Always replace the front sprocket and chain simultaneously for optimal drivetrain performance and longevity.
