Vortex Racing has been manufacturing championship-winning sprockets since 1995, and the 491AZR series continues that tradition of precision-engineered performance hardware trusted by racers and enthusiasts worldwide. A higher tooth count like 53T delivers a higher gear ratio, translating to stronger acceleration at the cost of top-end speed — a popular choice for track days, stunt riding, and spirited street use.
