Hub/Rotor 1979-81 M/C 5 on 5.00in BC

The Hub/Rotor 1979-81 M/C 5 on 5.00in BC by Allstar Performance is a purpose-built brake assembly for classic and vintage motorcycles from the 1979-1981 model years. This hub-rotor combination serves riders who demand reliable stopping power while maintaining period-correct fitment on machines with 5-lug, 5-inch bolt circle specifications. Whether you're restoring an original build or upgrading braking performance on a classic cruiser or touring bike, this component delivers the precise brake response expected from a trusted performance manufacturer.

Constructed as an integrated hub-rotor unit, this assembly combines the wheel mounting hub with the rotor friction surface in a single, balanced component. The 5-lug, 5.00-inch bolt circle ensures direct compatibility with factory wheel studs and brake caliper spacing on specified motorcycle platforms. The rotor face is engineered to dissipate heat effectively during braking cycles, reducing fade and extending pad life—critical for riders who depend on consistent braking feel across multiple ride sessions. At 17.75 lbs, the assembly achieves a balanced weight that minimizes unsprung mass without sacrificing structural rigidity or thermal capacity.

This hub-rotor assembly is essential for 1979-1981 motorcycle owners performing front-end rebuilds, brake system upgrades, or complete frame-off restorations. Mechanics and enthusiasts value Allstar Performance components for their exacting tolerances and proven durability in vintage and performance applications. Installation requires wheel removal and caliper bracket access; the bolt circle specification ensures no modifications to mounting brackets are necessary if your bike's original equipment matches the 5 on 5.00in standard. Proper brake fluid flush and pad bedding procedures are recommended after installation to ensure optimal stopping performance and safety.
