Engineered specifically for Harley Davidson applications, the Supersprox Stealth 51T rear sprocket addresses high-torque scenarios where belt drive systems may not meet performance demands. This dual-material design, pioneered by Supersprox since 1959, combines hardened steel teeth with an aluminum core to reduce rotational mass by 70%. The steel teeth feature a Black Tri-Zinc anti-rust finish, providing a robust surface that ensures smooth engagement with 530 chains to extend overall drivetrain life.
Structural integrity is maintained through stainless steel rivets that securely connect the components, while the precision-cut hub sizing ring ensures compatibility with both 1.99” (1984–1989) and 2.22” (2000–2025) wheel hubs. Available in anodized Black, Red, or Gold aluminum core options, this 51T sprocket is part of a lineup that also includes 49T and 53T sizes, offering riders a reliable, lightweight solution for optimized power delivery.
