The one-tooth reduction on the front sprocket tightens the overall gear ratio for improved low-end acceleration and throttle response compared to stock gearing. All components are engineered and quality-controlled by Vortex, a U.S.-based brand owned and operated by motorcycle racers and enthusiasts with nearly 20 years of experience in performance drivetrain components.
