Frequently Asked Questions

Will this fit my wheel hub?

Yes — the precision hub ring accommodates both 1.99" hubs (1984-1989) and 2.22" hubs (2000-2025). Verify your wheel hub diameter before ordering.

What chain size does this sprocket use?

This 51T sprocket is designed for 530 chain drive systems common on V-twin motorcycles.

How much weight does the aluminum core save?

The dual-material design reduces rotational mass by 70% compared to solid steel sprockets, improving acceleration and reducing drivetrain strain.

Will this sprocket last longer than stock?

Hardened steel teeth are engineered to extend chain life by providing a strong, smooth engagement surface for the chain.

Why is this called a 'Stealth' sprocket?

Supersprox developed the Stealth line specifically for Harley-Davidson and Indian V-twins, optimizing tooth geometry and material pairing for high-torque applications where chain drive outperforms belt drive.
