Bearing M/C Hub 1978-88 Inner

The Bearing M/C Hub 1978-88 Inner from Allstar Performance is an essential replacement component for classic motorcycle wheel assemblies spanning the 1978–1988 production era. This inner bearing serves as a critical load-bearing element in the wheel hub, supporting both radial and axial forces generated during acceleration, braking, and cornering. Whether you're restoring a vintage cruiser, maintaining a collector's bike, or performing routine hub service, this bearing replacement ensures smooth wheel rotation and eliminates play that compromises handling precision and tire wear uniformity.

Allstar Performance manufactures this inner bearing to OEM-equivalent specifications, utilizing precision steel construction and standard rolling-element geometry designed for the compact, high-speed demands of classic motorcycle hubs. The bearing's compact footprint—measuring 4.05 inches in width with minimal radial depth—fits the space-constrained environment of vintage wheel assemblies where hub bore geometry is fixed and tolerance stack-up directly affects brake rotor runout and sprocket alignment. The lightweight design (0.29 lbs) reflects the precision engineering required to minimize rotational inertia while maintaining the load capacity necessary for street or sport riding conditions.

Mechanics and enthusiasts working on 1978–1988 motorcycles will find this bearing suitable for front or rear wheel hub service, depending on the specific model's bearing configuration and application. Proper installation requires careful inspection of the hub bore for corrosion or damage, thorough cleaning with solvent, and use of appropriate bearing press tooling to avoid race distortion or premature failure. Pair this inner bearing with the corresponding outer bearing and seals to complete a full hub refresh, ensuring long-term reliability and eliminating the vibration, noise, or drag that signals worn bearing races.
