This kit gears one tooth down on the front sprocket compared to OE gearing (15T vs. 16T front), which tightens the overall gear ratio for improved low-end acceleration and throttle response. Riders should compare OE gearing to Vortex kit gearing to verify the gear ratio difference suits their riding style. GFRA (Go Fast) 520 conversion kits with further-reduced gear ratios are also available separately for maximum acceleration performance.
