Vortex Racing rear steel sprockets are engineered for riders who demand durability without sacrificing performance. The satin black electro-plated finish provides corrosion resistance, making this sprocket equally at home on the street or the track. Stepping up to a 51-tooth rear sprocket increases the overall gear ratio for stronger acceleration and more responsive throttle response.
